JGBP comment to JGMF "This from "cabdriver' in the Jerry folder at Deadnetcentral: "This Lion's Share gig (their closing week) was the first week of July, 1975.(week not correct) The Garcia-Saunders Band played two nights; the last night featured Elvin Bishop and John Lee Hooker. Along with Hooker doing his patented take-no-prisoners thing, Bishop and a couple other guitar players pulled of a sublime version of "East-West" in the closing set." I'm still trying to find the exact closing date for the Lion's Share, it was some time in 1975. I saw/heard Garcia & Saunders play on two consecutive nights there, during closing week. There were not very many people there, that's the funny part. And I can't find any reference to them doing those gigs anywhere. But it did really happen!"
