Common sense has officially left the building: Peabo Bryson was singing 'A Whole New World' at a sold-out concert, and some genius in the audience decided to hold up a neon sign that said 'Play Free Bird.' The singer actually stopped mid-song, pointed at the guy, and said, 'I don't think you understand the assignment, sir.' The crowd lost it, the guy got booed out of the venue, and now the video has 2 million views. Can we please teach people concert etiquette before they ruin another legend's set?
