Danny Says (unrated, 105 mins, ★★★)

Danny Fields, the gadfly-entrepreneur of US pop and proto-punk, is attracted to “crazy people”, he says, and the dark side of showbiz. As a music manager and all-round trend-setter he helped to launch Jim Morrison and his California combo the Doors, Andy Warhol’s hip inhouse band the Velvet Underground and such rackety Detroit acts as Iggy and the Stooges and MC5.

Admittedly much of this music now looks silly. Perhaps it always did. By the time Morrison hit Los Angeles in 1967, like a psychedelic Frank Sinatra, the hippie heyday had peaked and the acid trip was no longer so fruitful or freak-out free.
