1)  Grateful Dead fans are awful and I can't believe there are enough of them still alive that can afford this anyway.  You'd be doing them a favor.

2) Phish fans are just as bad but most of them can afford it because they are all trusties from the Northeast spending Dad's money.  They don't deserve this.

3) Watching internet meltdowns surrounding Trey, ticket prices, mail order, the "old days" and many other things these awful degenerate fanbases melt about is awesome, and cancelling these shows would guarantee even more.

4) The $ong$ aren't that good to be owed to anyway.

5) Widespread Panic rules.
