Last night, Dead & Company guitarists John Mayer and Bob Weir were the guests on Bravo series Watch What Happens Live with Andy Cohen. The two musicians stopped by the show’s clubhouse after their sets at NYC’s Citi Field, talking about music, fame, Mayer’s guitar face and more, as well as treating fans to a special performance.

After the thirty-minute program, the two sat down for a brief version of the hit Grateful Dead song, “Friend Of The Devil.” Watch the two famed musicians at work in the clip below.

You can also watch Weir and Mayer talk about gay bars, out of body experiences, Mayer’s solo album, and Jerry Garcia.
