On Aerosmith's Facebook page, the band updated: "Joe Perry is stable right now, with family and is under the best care. Thank you to all of the fans reaching out and sending their thoughts his way."

Bassist Tom Hamilton tweeted last night: "Thankfully, Joe seems to be better than we all first feared. Here's hoping he's back on stage soon, doing what he loves to do!"
Aerosmith frontman Steven Tyler wrote on his Twitter account: "Feel the millions of prayers coming your way. We all love you. Sending white light and all that I got your way."
Here's a video from an audience member which shows Perry appearing slumped on a portion of the stage at the Ford Amphitheater on the Coney Island Boardwalk before he staggers behind a wall on stage, where members of the New York police and fire departments attended to him.
