This is pure gold... once you know the back story.
Big bands do zillions of promo spots when releasing a new album, namely talk shows. Some are well equiped to host bands doing live performances, others are not.
A long story short, MUSE turn up for a performance on this Italian soccer/talk show and are told they will not be playing live and must lip synch to the original recording of the song. Taking offense to this (as any true musician would) they decide that if that's how it must be they will do it on their own terms... and swap instruments!
