Yep. (Pennywise is cool.... enjoy the show)
I've seen X, own nothing from them.
I've seen Felix Da Housecat, own nada.
I saw Social D twice, still own nothing...
I saw Spiritualized, own nada (don't really care to after that show)
I saw SuperSuckers once, own nada (but my GF does - does that count?)
I've seen Lenny Kravitz (for free), own nothing...
I've seen Peter Gabriel, own nada
I've seen Neil Young, own nothing... (does CSN&Y count?)
I saw Prince on his most recent tour, and until that night, I owned nothing (yet they were giving away his new cd when you walked in the arena - so much for record sales - they gave out something like 20K copies that night here in Dallas).
This isn't counting the festival shows like Ozzfest/Tattoo the Earth/Texxas Jam
I think that's it....
