[Linell]

My wife and I saw him play in New Orleans. Half way through the show his guitar strings broke and he stopped to fix it. The band kept playing, though.

A man in the audience stood up and started singing, and doing a very good job at it. The band picked up and followed the man singing, going right on through the song. Once his guitar was fixed, BB King came back in and sang backup for the man in the audience. His interaction with the audience for the entire show, and particularly this case, was amazing.
