Last week, Sean Lennon performed San Franciscos Red Devil Lounge. Lennon played two sets at the intimate venue: a headlining performance with the eccentric Vincent Gallo and an opening set with his girlfriend Charlotte Kemp Muhl as The Ghost of a Saber Toothed Tiger. During The Ghost of a Saber Toothed Tiger set, Bob Weir also emerged to join the couple for Oh Boy, Peggy-O and Big Boss Man. Weir and RatDog’s next tour will kick off in Jacksonville, OR on August 21. In addition, Weir will play a set with his old collaborator Rob Wasserman as Scaring the Children on September 12. The show will take place at Mill Valley, CAs 142 Throckmorton Theatre, with Jackie Greene supplying support duties.
