Last night, Lukas Nelson & Promise of the Real got some help from Grateful Dead guitarist Bob Weir at the second night of their two-show stand at San Francisco’s Great American Music Hall. The performance came as part of Promise of the Real’s stretch with singer-songwriter Tyler Childers on the ongoing “Stagecoach Spotlight Tour.”

Following sets by Childers and tour supporting artist Lillie Mae, Nelson and Promise of the Real came out for their headlining performance with Weir in tow. The band opened with a rendition of the Dead’s “Althea” sung by Nelson, before Bobby took over on vocals for “West L.A. Fadeaway”. Finally, Bobby stayed at the mic for a rendition of Bob Dylan‘s “Maggie’s Farm”, a latter-day live Dead cover and a staple of various post-Jerry Garcia projects. While Weir battled sound issues with his instrument throughout the sit-in, his presence at the Bay Area performance was nevertheless appreciatively received.

As JamBase notes, Weir and Nelson first performed together at a pair of recent tributes to Weir’s longtime friend and songwriting partner, John Perry Barlow, including Barlow’s free “Graduation From Meatspace” at The Fillmore and an additional event at Weir’s SweetWater Music Hall.
