Tyler also battled pneumonia before the tour began in June, while guitarist Joe Perry fought a knee infection."He does a lot of dancing on the stage and he does a lot of stuff with his mike stand. He put his stand down and twirled around and stepped backwards off the stage," Sanborn said.Tyler landed on a couple of fans, Sanborn said, and security rushed to help him. The crowd cheered when Tyler was helped up.The rocker was taken backstage, where a physician attended to him. Later, Perry told the audience the show would not go on.Jake Cohen was in the VIP area backstage and didn’t see the fall, but said he saw Tyler afterward."When they took him out, he was bleeding from his head and holding his shoulder," said Cohen, a salesman for Tyler’s Dirico Motorcycles line.Tyler, known for hits such as "Walk This Way" and "Dream On," promoted his motorcycle line at Sturgis last year and was back to do the same and play at Buffalo Chip.
