Nostalgia ain't what it used to be. But sometimes, if you've stayed home on a chilly Tuesday night, it's just what you feel like.
As it turned out, Dragon, the complete and utter and almost unbelievable history of a New Zealand band called Dragon, which screened on Prime this week, made for a quite wonderful nostalgia trip.
This hour and a half long documentary, which was plainly made with care and quite a lot of love, had everything: huge madness, big egos, bigger chart hits, bad drugs, awful tragedy, family squabbles, jealousy, more bad drugs, more tragedy, more chart hits and some of the most astonishing clothes and haircuts ever seen. It was, by turns, sad and uplifting, which is no mean feat.
Rock documentaries can of course be dreary, depressing affairs as anyone who has sat through U2's Rattle And Hum or Madonna's Truth Or Dare will tell you. They can be ploddingly predictable, Wikipedia-style bores too, a procession of bare facts and talking heads that will please only the band's tragics. Many play like This is Spinal Tap without the laughs.
But good rock docos are deep-fried gold. Remember Dig!? Brilliant. Oil City Confidential? Riveting. Don't Look Back? Terrific. The list of the good ones is longer than you think. Netflix has turned out to be an unexpectedly good place to find interesting ones. Two I've watched recently are the poignant and really rather sad journey through the life of jazz and blues pianist and singer Nina Simone, What Happened, Miss Simone?, and the surprisingly entertaining The Other One: The Long, Strange Trip of Bob Weir, about the Grateful Dead guitarist.
