Only minutes after guesting with Billy Joel on stage on Saturday night (November 10th) at Madison Square Garden, Aerosmith guitarist Joe Perry experienced shortness of breath and was treated by paramedics. Deadline.com reported Perry, who's now 68, performed "Walk This Way' with Billy and his band and ". . . was taken out of the Garden on a stretcher after paramedics worked on him in his dressing room, reportedly inserting a tracheal tube down his throat at one point."

Joe Perry's reps released an official statement on Sunday (November 11th), which read:

"Following a guest performance during Billy Joel’s show last night at Madison Square Garden, Joe Perry experienced shortness of breath and was treated backstage by paramedics who gave the guitarist oxygen and used a tracheal tube to clear his airway before taking him to a hospital. This morning Perry remains in the hospital where he is alert and responsive. The Aerosmith guitarist will be unable to appear today at Rock And Roll Fantasy Camp in Florida and apologizes to those attending. Perry is expected to return to the road later this month."

As most fans will remember, back on July 10th, 2016, Joe Perry collapsed during a Hollywood Vampires gig at Brooklyn, New York's Ford Amphitheater at Coney Island Boardwalk.

Alice Cooper, who fronts the all-star covers band, recalled to CBS News at the time that he was unaware that Perry was perhaps not geared up for such a rigorous schedule: "I didn’t realize Aerosmith only did two shows a week. Honestly, I just figured everybody was like me. I do five shows a week, and very physical shows. We were on our eighth show in 10 days. It was pretty brutal. I think (Joe) was dehydrated and basically exhausted. I talked to him before the show and he said, 'I don’t think I’ve eaten anything in three days.' I went, 'Well, that’s not smart.'"

Cooper went on to squash the rumors that Perry had collapsed due to a coronary, explaining, "It wasn’t his heart, though, and it wasn’t anything vital, because four or five days later he was on stage with us and I’d never seen him look so good."
