I'm currently reading Gregg's autobiography, "My Cross to Bear." Picked it up at a library book sale for a buck!
Even though I've been an ABB fan a long time, I'm learning a lot about his life. I'm at the point in the book where Duane is killed, and it's hard not to tear up at Gregg's recollections of this monumentally tragic loss.
But, back on topic, yes, the tribute concert was quite good. I may have to pick it up on CD at some point.
