I've seen a choice few musical concerts. I saw Jimi Hendrix somewhere around 1969 before he broke up with The Experience.
As I chronically hadn't much discretionary cash, I missed a lot of concerts. One I did see recently was one of my faves. Simon and Garfunkel in one of the re-union tours. When they brought out Phil and Don for 4-5 songs, Paul Simon said they were as excited as we were to see them perform.
