"You might think you know these photos pretty well, but the interesting thing is that if you scan them and then start looking at them on a computer screen, they reveal something new, and they really started speaking to me. There's one in particular of Mum on her honeymoon - Dad must've taken the photo, and she's standing in front of a car, and you can just see the ghosting of Mt Taranaki behind her, and there she is, a 26-year-old Irish woman, and I suddenly saw her as very separate to me, as a different person, but somehow she also seemed closer to me than ever. You think you know your mum, you think you know your family, but you sometimes get a shock of realisation when you see them as separate from you, and so that drew me in really."
Finn's mother passed away 15 years ago. He'd started writing a song for her at one point, and it was this seed of a song which helped get the music going.
"There were just a few lines I had: 'Hear the sound of the big parade, it's a sound I heard them playing in my sleep before the wind blew it all away'. And then I was walking along thinking of clouds and cloud shadows, because our family are quite newly arrived in New Zealand - Ken's family goes back about six generations, but we're only first generation, so we sit quite lightly on the land, and I was thinking about cloud shadows, and that image came to me. So it all started to come together."
He laughs at how odd it seems that he has become some sort of family historian, because it's not something he'd shown any particular aptitude for earlier in life.
"I was never the family historian in fact I was the opposite I suppose, I never kept anything, and I regret now that I don't have more of the old Split Enz T-shirts and things like that, just more stuff to share with the kids, so it seemed like I was perhaps an unlikely person to do this. But you can see evidence of it in my work too I suppose, certain songs where I reference growing up in New Zealand, and Neil similarly has that in his work. But it was great to have Ken to bounce off, and to examine his family history as well."
The show combines Finn and Duncum's talents in an immersive piece, with no fourth wall - Tim tells stories, sings songs, shares poetry, goes down tangents and sidesteps into explanations, engaging with the audience in an intimate way, while footage shot by his father Richard, along with work by choreographer and film maker Sue Healey, all shot on 8mm film, is projected on to a screen.
There's a loose narrative or dramatic structure, but it's primarily an exploration of identity, of connection with the land, with our various forefathers, and with each other, with fragments from family journals, letters and memoirs adding to the story.
"Connecting with the land and the landscape was a big part of it. I mean if I think about the number of times I've driven down to see Dad in Cambridge - he's still going strong - Neil and I do that journey when we're both in New Zealand, we both go down once a week or so. And that journey, the Waikato River and Mt Taupiri, Mt Pirongia, those kind of things that you see in the landscape, they also started to speak to me in a way that they hadn't before, because I was connecting them up I suppose."
"We're not trying to say to people 'this is what it means to be a Pakeha' or anything like that, we're just saying, 'We've got these photos and these home movies and these thoughts and feelings, and you've probably got them too, we're all the same in that sense', and so it's about finding the connections I suppose, and finding the things we all have in common."
Indeed Finn has found when performing the show previously at places like the Sydney Writers Festival and Galway International Arts Festival, that it stirs up people's own memories. People relate stories of their own mother or father, or talk about similar home videos, and generally feel encouraged to dig out some old photos, or at least reflect upon their own family history and identity.
"That's what we hope really, that there will be this gathering of stories. It's great to connect backwards. We all do it at different ages and stages in our lives. New Zealand is a young country, and like young people, you're always looking ahead, and thinking about what's next, and all of a sudden at some point you do take a little glimpse back, and that can be very rewarding. It's been a really pleasurable thing for me anyway."
