At first, I think George looks pale today, almost peaky, dressed in black with a baseball cap, a few straying grey hairs peeking out at the temples. Then the obvious strikes. He's not unwell. He's just not wearing makeup. No bold sweep of eyeliner; no dramatic waves of colour across the lids. No warming blusher. Oh, George can still be a drag queen when he wants. He just doesn't need to be. There is something stripped-back, a comfortable-in-his-skin quality that the absence of makeup is merely a symptom of.
At 16, he thought it was his divine right to walk down the street in Woolwich dressed as a nun. It still amuses him when people get outraged at his appearance. But he recognises the strange dichotomy of drag.
"You are wearing a mask, but on the other hand trying to draw attention, so it's a kind of, 'look at me, don't look at me'. I can laugh at some of the shit I used to do. I am grown-up now and I couldn't have said that 10 years ago. It would have been surrender, giving in. But it's so empowering to be able to say it. It's a wonderful thing."
He certainly has the life experiences of a grown-up. George was the anti-drugs 80s pop star and, later, successful club DJ, who fell long and hard into addiction. In 2006, after moving to New York with his musical, Taboo, he was sentenced to sweep the streets of New York for possession and, in 2009, was jailed in Britain after a bizarre case involving the false imprisonment of a 29-year-old Norwegian male escort and model, Audun Carlsen. After a drug-fuelled session with Carlsen, George accused him of stealing photographs from his laptop. He was sentenced to 15 months after handcuffing Carlsen to a wall and lashing out at him with a chain.
He once said addiction was a fundamental lack but has revised that view. "A lot of it is proximity. If you are around it too much, you are going to get dragged in. I don't put myself in those situations now. If I think people are going to get drugs out, I won't be there. There was a point where I was like, 'oh yeah, fine ... I don't do it'. But it's not fine. It's never fine."
Legally, he cannot talk about the case, though you sense he has a tale to tell. "I think it's very unfair of you to ask me," he says, apparently without rancour. (Later, I discover he was uncomfortable with several questions but, interestingly, there is no real visible sign; no strop.) But does he have an instinctive emotional response to the episode - perhaps regret or guilt or shame? "No, I don't think about any of those specifics. I think about consequences of my addiction generally. Everything that happened in life when I was addicted was a consequence of being an addict. When I first went to prison, I had a kind of sense of outrage and then I thought: 'actually, less is more'. That's one of the things I have learned in the last five years. Less is more."
He got clean the year before he entered prison. "That gave me a really strong place from which to encounter it. I got a job in the kitchen, had my own cell and made friends. I had to get used to being with me, learn to sort of like myself again." He read constantly - all the classics he claimed to have read already and never had - but television made him scream. "After a while I thought, 'f***ing hell, you've no idea what I am going through!'"
Prison developed its own normality. "That's the most terrifying thing about prison. I was only there about four months, but when it was time to go home I was thinking, 'oh my God, I've got to go out of here and deal with my life. I am not sure I want to leave'." Yet the experience changed him positively. "Once you get clear and get your head screwed on, you see the potential. You look at what you are doing and your behaviour. There was a big shift in me. I just thought, 'you are f***ing around. And you can't any more'."
The drama queen instincts have dissipated. "I look back now and most of the drama in my life was self-inflicted. I don't need to make up so much drama now. I watch my friends and think ... and? He said ... she said ... Twitter ..."
George was once king of the bitchy put-down - "imagine if one of your parents had been attractive" - but now opts for dignified silence, blocking unpleasant people on social networking sites. But he does admit it kills him not to have the last word. Part of him still wants to say: "You ugly bastard - f*** off!"
It's hardly surprising George once gravitated to drama. He grew up surrounded by it. I once interviewed his mother Dinah, a warm, chatty, Irish matriarch. (George loves and admires his mum hugely, but steered clear when he was messed up. She saw through him and he couldn't take the scrutiny.) Dinah suffered physical and emotional abuse at the hands of her husband, Gerald, who dominated the house but left her after 43 years of marriage. When Gerald died, the family did not recognise the saintly man described at his funeral.
Yet George loved his dad. "He was a formidable character who shaped who I am. If you can write someone off as a bad person then it's easier, but when someone is also great and noble and generous and kind and funny and contradictory, it gets harder. Now I think about the great things. I don't really think about him smashing the house up."
Childhood wasn't unhappy, but it was full of volatility, with his father's violence, his mother's attempted overdose (she's very different now, he says, very strong) and later, his brother's psychiatric problems. Only after his father's death did they achieve a real unity. "I think his death got everyone back together. Not consciously. I don't think anyone said, 'Dad's gone so let's get together' but I think we are a better family than we have ever been. In the past, everyone would turn up for a crisis. Now, we all turn up for dinner."
Surprisingly, his father was very supportive when his son came out. "I remember thinking, 'that's it, I'm finished. He's going to kill me.' But he was great," says George.
He loved music and dressing up, but was always conscious of being an outsider. "You are made to feel different long before you understand what it is. Other kids pointed it out. You don't walk like other boys. You don't talk like other boys. But at 6 you are not thinking about sexuality."
It has been suggested that he trawled the internet for partners and escorts, but he says it's not true and is typical of the way people stereotype gay sex. He subscribes to Eddie Izzard's idea that sexuality is like a ruler: homosexuality at one end, heterosexuality at the other - and lots of grades in between. Where is he? "Pretty gay," he laughs. Ever had a relationship with a woman? No, he says instantly - then hesitates. Well, there was his friend Alice, who was like a beautiful boy. "We had this sort of ... little ... I don't know what it was, really."
He is no longer certain he's ever been properly in love. "I'm not sure. There was a lot of drama. I have a more loving relationship with a lot of my ex-partners now I am no longer with them. I am really close to Michael [a former partner] and love having him around. I don't fancy him any more and I'm sure he doesn't fancy me, but the complicated stuff has gone.
I love him and care what happens to him." His last few relationships have dissolved quite healthily, unlike in the old days. "Not necessarily in the way I wanted, but I didn't go crazy."
This year, Culture Club will re-form for a 30th anniversary tour and album. Will it be difficult working with Jon Moss, Culture Club's drummer and the object of his affections and obsessions in all those early songs? No, but he admits their history gives him a certain frisson.
"It's a slightly weird experience. There's a kind of ... of course ... but I like it. I give a shit what happens to Jon. I regret a lot of the things I said. We experienced something so huge and magical together. I don't know if we understood what really happened. Sometimes, I think I know Jon better than I do, and then I think I don't really know him at all."
George walks me to the station, still talking. He doesn't need to, but he's kind in small ways, you can see that. And who would have believed that dignity would end up being so important to him?
There is something admirable about the unadorned George O'Dowd, the way he has turned himself inside out, then learned from it.
"It doesn't matter what has happened in my life," he says. "Right now, I am proud of myself. That's a great place to be. A really wonderful place to be."
