British glam rocker Marc Bolan and his band T. Rex are captured at the height of their fame in this 1972 concert movie by Ringo Starr. Two shows staged for the film at Wembley stadium yield spirited performances of “Jeepster,” “Baby Strange,” “Telegram Sam,” and “Bang a Gong (Get It On),” punctuated by agreeably silly vignettes reminiscent of Magical Mystery Tour. There’s a rollicking studio jam session with Bolan backed by Starr on drums and Elton John on piano; the oddest segment is a picnic where a butler flips burgers for a table of nuns while Bolan plays an acoustic guitar medley, accompanied by a string quartet. Part of a Rock ‘N’ Roll triple feature along with Head (see separate listing) and That Was Awesome.
