A singular wedding present given to Lisa and me all those years ago -- perhaps less appreciated by my bride than myself -- was a box of Betty Boards from my old friend Big Tom. Archive.org has long since superseded tape, but I still have the cassettes and the plastic cases with their hand-written set lists, and I have memories of listening to them in a rented Mustang convertible on our NoCal honeymoon, so, better than a chafing dish.
Anyway: "Obviously, this will end someday. There’s enough good material in the vault to go at this rate for another twenty or thirty years, or, at a slower rate, for fifty years."
I recently found the tapes of Allan Dodds Frank's multi-hour 1987 interview with Garcia, which he did after our much briefer backstage conversation (linked in the right rail). Ownership issues pending, I'll try to find a place to publish the transcripts and audio.
