Yesterday, popstrel Charlotte Church ed The Klaxons in an impromptu version of the band's new single Twin Flames. Both acts were appearing on BBC 5 Live's Richard Bacon show.
Although she and the The Klaxons had barely any time for a rehearsal - cramming in a news break - the performance was on the money. Take a look for yourself:
Church released her new album, Back To Scratch, this week.
