I would LOVE to see Kottke live! I had a co-worker that saw him and said it took a while to believe that he was really playing the guitar and not a pre-recorded track of two or three guitars. One of the reasons I play 12-string is Kottke's music.
As far as on-stage stories, I'd like to mention Angus Young. Maybe not the best guitar player on his own, but what a performer. I saw AC/DC in Phoenix, maybe around 98. About half way through the show the rest of the guys went off stage and Angus worked the crowd with some great solos and general "showmanship". As he went to one side of the stage, some punk threw a full glass (60 something ouncer?) of soda right in his face. Something popped on the guitar. The whole crowd was silent, it was eerie! The security guys started dragging the dude away and Angus waved them over. He pointed in the creeps face, gave him a few words, pinched the jerk's nose between his fingers, then went over to a crew guy with a new guitar and started playing as if nothing ever happened!!! Amazing!
On the bass side of things, I had the great chance to see John Entwistle and The Who in Vegas in 99. To this day he is the only person to walk on stage that has left me absolutely speechless. After that night, I know why he was The Ox.
