Duane Allman
A previously unreleased version of the song was included in Duane Allman's box set (Skydog, the Duane Allman Retrospective). As Scott Schinder states in his liner notes, "He (Duane Allman) also sat with the Grateful Dead on multiple occasions, an association that's represented here by an exhilarating, previously unreleased performance of the Dead's "Sugar Magnolia", on which Duane memorably trades licks with Jerry Garcia".
