Weir’s current band, Dead & Company — which features John Mayer in the Jerry Garcia role of vocalist and lead guitarist — played at Fenway Park on Friday and Saturday night. Per JamBase, Weir’s two-song appearance with McCartney marked the first time that members of The Beatles and Grateful Dead have shared a stage.
