well, if someone wanted to go through ridiculous means such as the san francisco cure promo show in feb 2000, it might not be so bad from that standpoint. if i remember correctly, one could only buy up to two tickets and you didn't actually get a ticket you got a wristband when you showed up and showed your id, so if you bought a ticket, you went into the show basically.
i mean, i guess that could only work for large-scale acts playing small places.... like if yanni were to play the 930 club.
