Zac Brown Band Welcomes Grace Potter & Amos Lee In Philadelphia

Zac Brown Band took the stage at The Mann in Philadelphia on Saturday. The group brought out opener Grace Potter and Philly native Amos Lee during the concert.

ZBB also performed material from 2025’s Love & Fear, including “Butterfly,” the band’s collaboration with Dolly Parton. Brown once again used the song to honor the late country music icon after doing the same two nights earlier in New York City.

The guest spots got underway with Zac Brown Band tourmate Grace Potter emerging to sing and play guitar on her rocker, “The Lion The Beast The Beat,” the title track of Grace Potter & The Nocturnals’ 2012 record. Following Love & Fear cut “What You Gonna Do,” Amos Lee emerged to perform his “Supply and Demand” during a stripped-down segment. “Supply and Demand” had been played 15 times prior by ZBB between 2013 and 2020, including several versions with Lee.

With Grace Potter in tow, the acoustic ensemble offered a take on the Bob Dylan/The Band sing-along “I Shall Be Released” in a reprise of a collaboration trotted out one night earlier at Forest Hills Stadium. Amos remained onstage for a cover of country singer-songwriter Paul Overstreet’s “Forever and Ever, Amen.” Zac Brown Band previously performed the song on June 9, 2011 with Randy Travis, the artist who popularized the song.
