9. Razorlight
After denying rumours the band was about to split, singer Johnny Borrell and bassist Carl Dalemo got into an argument on stage in Lyon which soon escalated into an all-out brawl.
After fists flew, Borrell took the mature decision to storm off stage. The rest of the band followed him, leaving the crowd staring into space. Eventually the quartet returned, sheepishly apologised and resumed playing.
