BTW, my first "big" concert was John Denver at the Garden in 1973 or 74.
Have also seen: Billy Joel (twice - one in a small concert hall in Hartford. Great show. Second time at New Haven Coliseum, after "The Stranger" made him a star)
The big Roosevelt Raceway concert in summer 1973 with CSN&Y, the Beach Boys with a cameo by Elton John on "Help me Rhonda", Joni Mitchell, and Tom Scott & the LA Express (when they were dating I think). Fantastic show.
Since then, in CA: John Mellencamp - he made some great anti-Clinton references, great show
Earth, Wind & Fire - also a terrific show
Moody Blues - aged, but still wonderful
Jimmy Buffett about six times - I know. I'm a piker.
James Taylor in Sept. 1995, when he previewed the songs from Hourglass, just wonderful
James Taylor not too long after September 11th, with my son. That was his first concert. :-)
Mellencamp is anti-Clinton? That's suprising since he's a self-proclaimed liberal.
I'll have to play his CD again.
