Nowadays since Ticketmaster sells all the tickets to their own distributor to scalp for 5x the face value, if the band cancels you only get the face value refund.. They could make a helluva living just scheduling and canceling shows over and over..
Or could be like Elton john.. I bought tix for my wife like 5 years ago and he cancelled 3-4x but they wouldn't issue refunds so they had my money for, like, 4 years ($1000) with not mention ,at all, if they would honor them when he actually played.. They did, so we got lucky..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
