Quadrophenia was made only 15 years after the events portrayed in the film so for a 15-20 year old in 1979, some of us were barely out of nappies and short trousers. It'd be like going to see a film about Blair's "Cool Britannia" of Pulp, Oasis, Blur etc. People in their early 30's would be fine combing it and others, like the young 'mod' that came on here attacking mid 70s retro dressers would have zero reference points, apart from the ecstasy addled recollections of their big brother/uncle about the seismic shifts in the fabric of British society that took place at the turn of the milennium, bla, bla, bla.
