Lukas Nelson & Promise of the Real brought their summer tour to Long Island this past weekend for a two shows at The Stephen Talkhouse in Amagansett, NY, and Sunday’s performance featured two special guests, Warren Haynes and Jimmy Buffett.

Buffett was the first sit in of the night, joining Nelson and company for his own classic “Margaritaville.” Haynes emerged at the end of the night to help Promise of the Real close out their set with a cover of Neil Young’s “Cortez the Killer” (Lukas and POTR have recorded and toured with Young several times in recent years).
