Warren Haynes hosted his 28th annual Christmas Jam last night. The Christmas Jam and the Pre-jam have become one of the most anticipated events of the season and promise to be chalked full of surprise jams and once in a lifetime collaborations.

To raucous applause, Bob Weir came out during the opening chords of “Sugaree” last night and one of those special Christmas Jams moments was eminent. Bob was supported by Eric Krasno, John Medeski and George Porter Jr. for the classic Dead tune. As the song closes out, George Porter Jr. turns to the crowd to sing out the song.
