Everything has changed - we can make the sound as good as possible. My first concert was January 24, 1966. I didn't discover that live tapes existed until 1974. Playing in the band is the ultimate anthem for the Dead. You'll always hear this in the best concerts.
Every song has value.
I'm for all the tunes - I never wanted to hear anything specific. All I wanted was for them to play it well. There are tapes of the NRPS opening in the early 1970's. They didn't play every show and there were a lot of shows missing. It appears that the last year of their playing - not much was of my standards for high achievement.
