Bob Weir sat in with Taj Mahal during his solo performance at the the Sweetwater Music Hall in Mill Valley, CA last night. Jambase reports that the guitarist made his appearance for “Little Red Rooster,” “K.C. Moan” and “Good Morning Little Schoolgirl.”

Weir, who is a part-owner of the Sweetwater Music Hall, has been joining a number of acts at the venue lately. Last week he took the stage with Dark Star Orchestra and Blackberry Smoke, and he will likely perform with the Preservation Hall Jazz Band tomorrow night.
