Gregg Allman and Warren Haynes played a mini-set at New York’s the Best Buy Theater last night. The performance helped raise money for the Country Music Hall of Fame and Museum, which hopes to complete a major expansion. A number of musicians with ties to the country world performed at the event, including Jason Aldean, Emmylou Harris, Rodney Crowell, Vince Gill, Ashley Monroe and Pat Monahan. The entire ensemble remained onstage during each individual performance.

Allman and Haynes—who are in New York for The Allman Brothers Band’s annual Beacon Theater run—closed the evening with a five-song acoustic set. They opened their performance with Allman’s take on Jackson Browne’s “These Days,” before running through “Melissa,” the Garth Books hit “Two of a Kind, Working on a Full House,” “Midnight Rider” and “Long Black Veil.” Haynes actually co-wrote “Two of a Kind, Working on a Full House” during his time as a Nashville songwriter.

Some unique collaborations took place, too. Aldean joined Allman and Haynes for “Midnight Rider” while Joan Osborne sat in with Emmylou Harris.

As previously reported, The Allman Brothers Band will debut two new songs and seven covers at the Beacon this year.
