Aerosmith guitarist Joe Perry recently did a recording session with Paul McCartney.  In an interview with the Chicago Sun Times, Perry was not willing to give a lot of details.  But, the guitarist did tell us that an announcement could be coming.

Perry says:

"I did a [recording] session with Paul McCartney a month and a half ago for a private thing.  I met him once or twice [over the years] to say hello. To spend 6 or 8 hours in studio with him recording! He makes you feel like [you’re recording with just another guy]."

Alice Cooper and actor Johnny Depp were also at the recording session.  Perry says, "the three of us are looking at each other like, hey, we're sitting here with Paul McCartney!  And we're all looking at each other like open-mouthed kids."

The project is "under wraps for now."  But, Joe Perry says to expect an announcement when the time is right.
