Spending $100.00 per concert ticket to see your favorite artist. You wait all night to hear your favorite song by one of your favorite artists and the big moment comes. Then, the artist points his mic out to the crowd and implores the audience to sing your favorite song by one of your favorite artists. $100.00 to hear some drunk behind you sing as loud as they can, off key. Heard Tom Petty do it (Breakdown), The Monkees (Daydream Believer), Ringo (Yellow Submarine), Bad Company (Rock & Roll Fantasy), Brian Adams (Summer of '69). I believe I'm paying big bucks to hear the dude on stage perform the songs, not some random slob bellowing like a elephant seal. It would be like Ian taking a play off and letting someone from the crowd throw the next pass. Yes? No?
