Last week, Tom Hamilton’s American Babies hinted at a special guest for their Grateful Dead Masquerade Ball at Sweetwater Music Hall tomorrow, and now the band has confirmed that the guest will indeed by venue proprietor Bob Weir.

In a Twitter post, the band shared a photo of Hamilton and Weir practicing for their upcoming Los Muertos Con Queso destination event and announced that Weir will join them “for a few songs” tomorrow night.

American Babies will also play a show at Sweetwater this Saturday, November 19, with special guests Dave Schools and Holly Bowling. Doobie Decibel System will be handling supporting duties on both nights.
