I would also watch the pre-show interview. There is a humorous interlude where Ken Babbs is trying to MC for the Dead, and Ken (along with Ken Kesey's sister in law) will be on the pre show.
The pre shows are nice, we almost never get to hear these people talk (including all the previous pre-show interviewees) and I think it is important we get to hear their thoughts, and for the younger generation (dang, did I say that? Must be getting old) to make a deeper connection to the music.
They gotta get Mr Wickersham on there..I would love to hear that!
Thanks Grateful Dead for keeping life interesting!
