STURGIS, S.D. — Aerosmith's Steven Tyler suffered head, neck and shoulder injuries in a tumble from the stage at a South Dakota show, a concert spokesman said Thursday, and the audience thought it was part of his hipshaking act until he didn't get up. Tyler, 61, fell while entertaining the crowd by dancing around as the sound crew replaced a fuse that blew during the song "Love in an Elevator," said Mike Sanborn, spokesman for the Buffalo Chip Campground, which hosted the Wednesday night concert. An amateur video showed him spinning around before falling off the stage.
