Callow Followill is back onstage following a "freak accident" that broke his foot in May. He performed with Zach Bryan and Bruce Springsteen, singing the latter's "Atlantic City" on Sunday, July at MetLife Stadium in New Jersey.

Zach Bryan concluded his three-night stand at New Jersey’s MetLife Stadium on Sunday night (July 20), and to mark the occasion, the country superstar surprised the sold-out crowd by bringing out special guests Bruce Springsteen and Caleb Followill from Kings of Leon for a couple memorable performances.

The Boss joined Zach Bryan and Caleb Followill of the Kings of Leon for a rendition of his 1982 classic 'Atlantic City.'
