Cooper made the revelations to Billboard ahead of his performance at the grand opening of John Varvatos' new store in Detroit last Thursday (April 16th). "The album's done. It's mixed, ready to go and I'm very, very happy with it," Cooper told Billboard.

"I'm really happy with all the stuff on it. McCartney's on it. Zak (Starkey)'s on it. Dave Grohl is on it, (AC/DC frontman) Brian Johnson -- and in places where you wouldn't expect them to be, that's the cool thing."

Aerosmith's Joe Perry has previously revealed that he, McCartney and Johnny Depp have recorded a cover of the Badfinger hit "Come and Get It" which was written by McCartney.
