Iggy Pop has covered an Elvis Costello song taken from the musician’s latest album, ‘Hey Clockface’.‘No Flag’, which is the second track from Costello’s album that was released in October, has been re-versioned largely in French by the punk legend.Costello said in a recent Musician on Musicians interview with Iggy for Rolling Stone that the original ‘No Flag’ was a nod to Iggy And The Stooges’ 1969 classic ‘No Fun’.The artist told Pop he was surprised no one had picked up on the link.
