The worst concert I ever attended was an Eric Clapton concert in 1979 in Mobile, Alabama.
The 2nd worst was Bob Dylan Hurricane Carter concert in 1975 in Houston, Texas.
The best concert ever was Led Zeppelin at the Fillmore West in San Francisco in 1969.
I saw the Who at the Hollywood Bowl in 1967. The other acts were better (Everly Brothers, Sunshine Company, the Animals).
Went to 6 Grateful Dead shows and 11 Jerry Garcia Band shows, don’t remember a thing.
Elton John was the best show I attended.
