Saw the J. Geils Band around 1976, with opening act the James Cotton Blues Band. What a great concert!Aside from the obvious 60's Beatles, Stones and Who choices (keeping in mind that Jagger has said the Who were the best live band of all of them), here are my dark horses
- I'd love to have seen the J. Geils Band in their 70's prime.
- Duke Ellington in one of his dance hall gigs.
Also, Big Country's early 80's New Year's Eve gig that was shown on MTV (and still can be found on YouTube). That just looked like an incredibly fun time.
