I saw Arlo Guthrie, Country Joe, Melanie, and what was left of Canned Heat at Brooklyn Woodstock in 1994. I have the bandana I got there somewhere. I saw The Band at Beacon Theater the same year.
I’ve seen The Who, in the late 80s with Kenney Jones instead of Keith Moon.
I’ve seen Crosby, Stills, & Nash, but not Neil Young (though I work with a guy named Neil Young…but I don’t think he plays guitar).
I somehow missed out on all of the 8,376 shows the Dead played in Sacramento over the years, but I did see Dead & Company a couple years ago.
Guthrie/Santana/Dead
Grateful Dead in 1994 and the Who in 2002, second show after John Entwistle died.
