After canceling his show Wilmington, NC due to health reasons, Gregg Allman also canceled his set at FloydFest over the weekend, with the famed Allman Brother slated to headline Saturday’s festivities.

Instead, Keller Williams and Leftover Salmon came together for a collaborative set dubbed the “Buffalo Mountain Jam” that saw them pay tribute to Allman with a Williams-led rendition of “Whipping Post.” Other highlights from that set according to The Roanoke Times included appearances from Elephant Revival and the T Sisters along with a cover of “Nobody’s Fault But Mine” led by Pimps of Joytime singer Kim Dawson.

Prior to that, Allman’s former ABB bandmate Warren Haynes also tipped his cap to the ailing Allman by covering “Jessica” with his Ashes & Dust band.
