DO NOT JUMP ON STAGE! It can't be said enough, because you could get hurt, the band could get hurt, and security will not be kind. This is a once in a lifetime exception.
A guy jumped on stage during Bastille's show last night in Scarborough to propose to his lady. Security was dragging the guy back and he's lucky that Dan Smith stopped them. Here's the video of what happened and again...DO NOT JUMP ON STAGE!
