It seems not everyone's happy about Coldplay's track Viva La Vida, least of all the band Creaky Boards who claim in this video that they wrote it. The clip also alleges that Chris Martin nicked the tune when he saw them live at New York's CMJ music festival in October 2007. A case of musical theft? Hmm, maybe not. Coldplay have denied the allegation, saying that their track was written and demoed in March 2007, a full six months before Creaky Boards say Chris saw them play.
