Grace Potter and The Nocturnals got some help from a surprise guest Saturday night at their Grand Point North Festival in Burlington, VT. The band was joined by country music superstar Kenny Chesney, who took the stage for “You and Tequila,” a duet that he recorded with Potter in 2010, as well as a take on Bruce Springsteen’s “I’m On Fire.”

This year’s Grand Point North Festival featured performances by a number of acts including Gov’t Mule, Trombone Shorty & Orleans Avenue, Charles Bradley and His Extraordinaires, City and Colour, The Felice Brothers and Shovels & Rope.
