There are always rude people at concerts - don't know what makes people want to GO to them, if all they're going to do is talk, heckle, etc.
I was at a solo Jon show in Atlanta with some awful people sitting in back of me - talked incessantly, runs back and forth throughout the show for beer (as if they needed anymore) - I just wanted them to SHUT UP so I could hear the show!
And at a Yes show in Chicago, there was a woman talking the whole time behind me - finally I could stand no more, and neither could Arlene, who I was with - we both turned in unison and yelled "WILL YOU PLEASE SHUT UP!!"
Actually, she did . . . I was amazed . . .
If all you want to do is drink beer and talk, and you don't even like the band you're hearing, then just stay home . . .
