Forty years ago this weekend, Marc Bolan died in a car crash at the age of 29. This documentary uses Marc’s words, from diaries and interviews, as well as contributions from producer Tony Visconti, close friend Steve Harley and Toyah Willcox, who was a fan in her teens.

The self-styled ‘dandy in the underworld’ borrowed from Elvis, James Dean and Rimbaud among others, and more than one interviewee here credits him with being the first glam rocker.
