Sorta reminds me of seeing Johnny Winter about 10 years ago. Only one of a few live professional performances I didn't watch until the end. No fuel in the tank whatsoever. Sorry to hear the great B.B. King didn't know when it was time to exit gracefully.
Huh,
I saw Johnny Winter about 6 maybe 7 years ago at a relatively small theater. His band warmed up the crowd with about three really solid tunes and then they brought out a chair, and Johnny. He was slumped over two guys shoulders as they carried him out and sat him in the chair and then put his guitar in his lap. I immediately though that it was the "one last tour before I die" type of deal but man was I wrong. Sure he had lost some of his luster from the 70's (happens to everyone), but man the guy could still play some pretty mean and pretty fast stuff on his guitar! I left impressed.
