Gregg Allman sings “Gone to Shiloh” with Elton John and Leon Russell in October

Gregg Allman sat in with Elton John and Leon Russell at New York’s Madison Square Garden last night. Though billed as an Elton John show, Russell sat in for a third of the show. Allman emerged partway through the night to sing with Russell and John on “Gone To Shiloh.” The three musicians collaborated on the same song—which appears on the new Elton John/Leon Russell album The Union —last October in both Boston and New York during T Bone Burnett’s Speaking Clock Revue. Burnett also produced Allman’s new solo album Low Country Blues.

Russell is in New York for his induction into the Rock and Roll Hall of Fame. Allman—who enjoyed a night off from the Allman Brothers Band’s Beacon run—attended last night’s show with his son Devon.
