Bob Weir has had a busy October so far. The Grateful Dead founding member at large has been playing at Terrapin Crossroads with Phil Lesh, paying tribute to Tom Petty at Sweetwater Music Hall and other surprise sit-ins in the bay area.

Lukas Nelson, son of Willie Nelson, and his band Promise of the Real was playing a Hardly Strictly Bluegrass after-show at Slim’s in SF. Bob Weir having played earlier in the day at the festival, made his way to the Lukas Nelson gig for a few songs. Among the songs they played, was a rocking version of the Grateful Dead classic, Althea. Bobby donned the slide and shared vocal responsibilities with Lukas.

Thanks to Coton Tzu, we have some great front-row footage of the sit-in!
