It sounds like a decent line up. The important thing would be the Tribute Concert itself, right? It should be interesting to see live or on tape.
Yes, you're right... a fitting tribute concert is the most important thing. The only reason I even brought it up is that I found it funny that Travis participated in the first place, due to his "notoriety" on various drum forums, and that this was a gig that was completely out of his "normal" style. As I understand it, he contacted Dwight Yoakam about playing it. Dwight had originally wanted Don Henley, who was unavailable.
The quote from Buddy Alan Owens in my local paper was basically, "this tattooed kid came in and nailed the drums, EVEN the mistakes from the original recordings". Personally, I find the whole thing refreshing, because Travis usually gets beat up on the forums. He did a gig out of pure love for the music, and he did it well. Sounds like a pro to me!
