Bruce Springsteen is known for inviting anonymous audience members onstage during his concerts – but you might recognize the latest person to join him up there. Bob Seger came out of the crowd last night during Springsteen's concert in Detroit, coaxed forward by guitarist Steven Van Zandt from his front-row seat.

Seger -- who lives near the Palace of Auburn Hills, where the concert took place -- played a tambourine for the rousing, show-closing cover of the Isley Brothers' "Shout." You can watch his performance with Springsteen in the video above.

This impromptu collaboration provided a happy ending to a concert that also included a cautionary warning from Springsteen. Just before launching into "Born in the U.S.A.," he told the crowd that their legislature was considering LGBT-focused measures similar to the ones that forced him to cancel his show in North Carolina last week. "We hope the bill doesn't pass, 'cause we love playing in Michigan," he said. "So keep your heads up."

Springsteen had been set to perform on April 10 in Greensboro. Ringo Starr also canceled a North Carolina concert over the legislation. Gregg Allman and Jimmy Buffett have also issued statements opposing the law, which is known as HB2. State officials have since announced a plan to soften their stance.

Springsteen is touring in support of an expanded reissue of 1980's The River that came out late last year. Coincidentally, Seger joined Springsteen onstage during the original tour too, joining him for an encore reprise of "Thunder Road" on Oct. 3, 1980, in Ann Arbor.
