Iggy Pop at 70: Still the ultimate performer

Get your head round this: Iggy Pop was born on 21 April 1947. Yes, that makes him a septuagenarian.

Anyone who encountered Iggy in the early Seventies when he was without a record label, of parlous health and calling himself "the world's forgotten boy" would have been amazed not just that he had reached 70, but was also fighting fit and respected as one of the all-time great performers.

So, BBC Arts salutes James Newell Osterberg. More importantly, so does Chrissie Hynde who, in a special film below, details what makes him the ultimate performer.

And for further proof, there's a fistful of Iggy's greatest performances, ranging from unhinged crowd surfing at the 1970 Cincinnati Pop Festival to a rip-roaring reunion with the Stooges performing Dirt at Glastonbury in 2007 plus two classic songs from an Old Grey Whistle Test appearance in 1979.
