Bob and Shrooms were arguing over which was the better performance of "Deal"--the one recorded in Philly on July 16, 1977 or the version recorded at the Meadowlands on August 23, 1983. Bob was totally convinced the Philly version was the better of the two, while Shrooms was equally adamant that the Meadowlands version was superior in every way.
Shrooms: "If only Jerry were here to settle our argument."
