When Bruce Springsteen isn't playing his beloved New Jersey, well, everything else looks kind of the same to him.

The Boss greeted his audience Friday night in Detroit with a hearty, "Hello, Ohio!"

To make matters worse, he kept it up for a half-hour before catching the mistake, aided by a discreet correction from guitarist Stevie Van Zandt.

Springsteen apologized, telling the crowd, "That is every front man's nightmare."

He made up for the gaffe with a solid midshow selection of Detroit songs.
