This past weekend at Indianapolis, IN’s White River State Park, WTTS Rock on the River, which benefits the Indiana Children’s Wish Fund featured headliners The Revivalists, who delivered a finale set that featured guest spots from Marcus King and Robert Randolph, both of whom led their own bands earlier in the day.

As JamBase reports, the New Orleans-based headliners brought out King for a run of their own “Soul Fight,” while Randolph lent his soaring slide to The Revivalists’ hit “Wish I Knew You.” The two guests also had a run in earlier in the day, as King joined Randolph and his Family Band on a cover of “Hey Joe.”
