Stevie Ray Vaughn in the Paramount when he was doing Hendrix.
Santana in the arena.
Zep, The Who/Clash, Stones (lump these together because the shows were great but the sound sucked)
BB King with Kenny Wayne Sheppard
ZZ Top
George Thorogood
Robert Cray

(I can't pick just five)

only regret: not seeing Pink Floyd

Embarrassing concert: My mom forced me to see Ricky Nelson when were on vacation in California. At least I was out of state so not likely to be seen at the Garden Party.

BTW, my mom was driving to see Buddy Holly, Ritchie Valens and the Big Bopper when their plane crashed. I wish she had kept the tickets.
