Commemorate the recently deceased Malcolm McLaren—punk-rock impresario and genius of cultural manipulation—with this bit of glitter and garbage from 1980. Filmed after Johnny Rotten left the Sex Pistols, The Great Rock 'n' Roll Swindle is trapped somewhere between a documentary, a mockumentary, and a desperate bid to squeeze the last few pennies out of the band's notoriety. But there are diamonds in that dung heap: Sid Vicious singing "My Way," guest appearances and vocals by fugitive train robber Ronnie Biggs, and a performance of "Belsen Was a Gas," perhaps the most offensive song in the history of sound.
