No Lesh as per the Lost Live Dead Blog:"May 22, 1981 Fox Warfield Theatre, San Francisco: Jerry Garcia, Bob Weir, Bill Kreutzmann and Mickey Hart/Holly Near/Norton Buffalo and Merl Saunders/After the Grateful Dead re-introduced their acoustic lineup at the Fox-Warfield Theater in September, 1980, they realized the more streamlined acoustic configuration was a more viable lineup for benefits. Less equipment and more modest expectations made the show less of an event, while still capitalizing on the Dead’s drawing power. Keeping with their Bay Area policy, whenever they were billed as other than “The Grateful Dead”, fans expected something different and less dramatic than a full Grateful Dead electric extravaganza.After a low-key SEVA benefit at Berkeley Community Theater, on April 25, 1981, featuring only Jerry Garcia and Bob Weir on acoustic guitars, John Kahn on stand-up bass and Bill Kreutzmann and Mickey Hart on drums, the band had a somewhat higher profile event at the Fox-Warfield (the theatre, at 982 Market Street, did not change its name to The Warfield until a few years later). An anti-nuclear power (No Nukes) benefit was held, with “Jerry Garcia, Bob Weir, Bill Kreutzmann and Mickey Hart” as the headline act. There were a number of interesting aspects about this show that remain unreported, since it was not a high-profile show outside of the immediate Bay Area (and there being no internet and all). Specifically, there was a one-time Grateful Dead configuration, and the first and best appearance of a band later known as High Noon.To dispense quickly with the Grateful Dead part: the band came on last, introduced by Wavy Gravy as “Captain JerryBobKreutzHart,” taking care not to call them the Grateful Dead. Brent Mydland was on board playing acoustic piano, but John Kahn remained on acoustic bass. Of course, this was a West Coast perception, as between the two acoustic benefit performances there had been an entire East Coast tour, but for most people in the Bay Area John Kahn had been on bass the last time we saw the Dead.Some time later I asked Dennis McNally why Phil hadn’t played those shows, and Phil had apparently told Dennis “because no one asked me.” Thus this show and the April 25 BCT show have to stand as Grateful Dead shows without Phil Lesh, making them unique indeed. The actual performances were quite good (you can decide for yourself), but the fact that Kahn played bass instead of Phil seems somewhat forgotten—certainly it isn’t noted on Deadlists or Archives."It is nowThanks for the great blog.
