Bruce Springsteen bellowed "Hello, Ohio!" to his fans at the Palace of Auburn Hills. That's in Michigan.
The 60-year-old rock legend referred to the neighboring state several times Friday night until E Street Band guitarist Steve Van Zandt whispered in his ear.
A visibly embarrassed Springsteen grinned and said such a mistake was "every front man's nightmare."
The Detroit Free Press says Springsteen rocked the forgiving audience for nearly three hours with new and old hits, including a complete performance of his album "Born to Run."
