Alice Cooper made a surprise appearance during Motley Crue's pre-show appearance at the Hard Rock Café in Stockholm.

Cooper, who's serving as the support act on the band's Final Tour, helped out on four songs: "No More Mr.

Nice Guy," "Be My Lover," "Lost in America" and "School's Out."

The pre-show event came ahead of the band's main gig at Stockholm's Ericsson Globe venue.

Crue and Cooper pick up their tour on November 18 at Helsinki, Finland's Hartwall Arena.

The trek - the final for Crue - wraps with a three-show run at L.A.'s Staples Center from December 28-31.
