It would be nice to be able to believe that Motley would do something to help out young/new bands, but I'm not surprised it went down like that. When is the last time anyone in that band did something that didn't benefit them?
I don't want to catagorize all bands with Motley, or others that do what they did, but it seems today everyone loves bitching about the state of the music business, but no one does anything about it. Charging $20 for a cd and $40 for a shirt alone makes me realize they don't care. I remember concert tickets for $15 bucks and tour programs for $8. I don't know how kids today get to see all their favorite bands now.
But good for you for "winning" (and I mean that because of all the trouble you had to deal with) and maybe down the road you'll see some benefit from playing the show. At least you have the experience of playing in front of all those people.
