Gene Simmons might not seem like he'd have much in common with a veteran adult-contemporary crooner like Englebert Humperdinck, but appearances can be deceiving.

Simmons and Humperdinck are collaborating on a track for the latter's upcoming duets album, which also includes performances by a number of other surprising artists. Humperdinck broke the news during a recent interview with Noise11, enthusing about the guest list on the record, which is due in October. You can watch the video above.

"Isn’t that something? It is going to be very exciting," Humperdinck said of the Kiss member's involvement. "There’s Elton [John], there’s Smokey Robinson, there’s Willie Nelson, Kenny Rogers and Neil Sedaka, and it goes on and on and on. It is very exciting names on this particular album. I’m so thrilled that everyone has responded and wanted to work on the album with me, and I think it has been a very exciting project."

The album could mark a return to the charts for Humperdinck, who's maintained a presence as a steady touring act since his '70s heyday, but hasn't had a truly high-profile song since he contributed his version of 'Lesbian Seagull' to the 'Beavis & Butt-Head Do America' soundtrack in 1996.
