On Nov. 25, Bob Weir made a surprise appearance at Sweetwater Music Hall, sitting in with Lukas Nelson for a trio of songs (including Bob Dylan’s “Desolation Row” and “It’s All Over Now Baby Blue as well as George Harrison’s “My Sweet Lord”) during a benefit for the Music Heals International organization.

Billed as Lukas Nelson & Friends, the house band included Dan “Lebo” Lebowitz, Steve Adams, Ezra Lipp and more.

Jay Blakesberg was there to capture all the action.
