Steven Tyler is injured on stage. The frontman for Aerosmith was performing for a big crowd at the Bike Rally’s in Sturgis, South Dakota when things got a bit tipsy. Steven appeared to fall backwards, and not in a stage dive to the crowd.

People watching the concert said that Steven went out on a catwalk by the stage, but then fell over backwards. From the Associated Press:

Tyler was on the stage’s catwalk when he fell backward onto a couple of fans in the middle of what was a record crowd, Sanborn said. Security rushed to help him and the crowd cheered when Tyler got back up.

“He was good natured about it,” Sanborn said. “He was in good spirits when he got in the helicopter. He was talking and joking with the physician.”

“It was an unfortunate end to an extraordinary evening.”

Tyler suffered minor head and neck injuries and a shoulder injury, but it wasn’t immediately clear how serious that was, he said.

Tyler was taken backstage and around 12:15 a.m., Aerosmith guitarist Joe Perry came out to tell the audience Tyler was being taken to the hospital and that the show would not go on.

Let’s start the speculation now. Was Steven drunk? Was he under the influence of something else? He hasn’t been out of rehab that long….
