Perry, who sings on four of the tracks, also expects to tour early next year under the guise of the Joe Perry Project. "Have Guitar � Will Travel," a nod to the similarly titled 1959 Bo Diddley album, was named by a fan, Joe Piscitelli, after Perry asked for submissions via Twitter.

Five of the tracks are sung by a relatively unknown German musician called Hagen. He was discovered by Perry's wife, Billie, on YouTube. - more on this story
