Jazzy:
To get a good approximation of a live Dead show on a good night, listen to Live Dead, a double album from the Fillmore in 1969 - one of the recording crew was our very own Ron Wickersham - especially Dark Star/St. Stephen/The Eleven (so named because it is in 11/4 time).
My name is Bill, and I am an unrepentent Deadhead.
Bill, tgo
