Bob Weir revived his collaboration with Dumpstaphunk for their Halloween show at Sweetwater Music Hall.

This marks the second Halloween in a row spent with Dumpstaphunk as Weir joined the band on a selection of covers like “Don’t Do It,” “Iko Iko,” “Maggie’s Farm,” “Shakey Ground” and the Dead’s “Shakedown Street.”
