Furthurmore Friday Week 38



For the 38th Furthurmore Friday, we have the following contest:

In the 1970's, there is only one known instance of any Grateful Dead music being played with a bass player other than Phil Lesh, who sat out a couple of songs at this show to let this very special guest take over bass duties. At what show did this take place, and who was the guest bass player?

Of the first ten correct answers (Berry Oakley, on July 16, 1972, Dillon Stadium, Hartford, CT), Jay M. was chosen at random and won a Furthur 2010 Radio City poster.
