Bands/artists you never got to see live in their heyday, but would've liked to.

Might be the right description shdog, but definitely a predictable response from good old Schubert.  

I missed ever seeing Waylon Jennings or Buck Owens, regret that.  

I have seen all on your list but I wish I could have seen.
Hendrix, Joplin, The Doors, Van Cliburn, Bill Evans, John Coltrane.

Hendrix, and Janis Joplin for sure. I really like Merle Haggard too. Chet Atkins and Marty Robbins. I'd like to see again but can't Prince.. He put on a killer show. I liked Salina too. What a bad thing to happen to such a shining star.. Patsy Cline and Billie Holiday. I'd give my eye teeth the see Pavarotti again...

Regards

i saw  Chet Atkins  a few times and have his autograph on my Larrivee guitar
