According to Van Halen News Desk, Gene Simmons's long-promised box set of previously unreleased solo material, "The Vault", will contain three KISS demos that he recorded with the Van Halen brothers — guitarist Eddie and drummer Alex.
Gene reportedly sings and plays bass on the material, which was laid down in 1977 at the Village Recorders studio in Los Angeles during the writing sessions for KISS's "Love Gun" album.
Gene, Eddie and Alex cut "Christine Sixteen" and "Got Love For Sale", both of which appeared on "Love Gun", and "Tunnel Of Love", a tune Simmons would re-record for his 1978 eponymous solo album.
"They did me a favor," Simmons told Rolling Stone in a 2016 interview. "We recorded three songs I had written. I was in Los Angeles between tours, and I called Alex and Ed: 'Listen, I got three songs. I'm going in at 2 a.m. Do you want to come down and help me?' Usually, I play the guitars and the drums to the extent I can and put down all the parts. But I wanted to do three songs instead of one. So we did 'Christine Sixteen', and I put the keyboards on, everything else. And Ed did the solo to the rhythm guitar, bass, and Alex was on drums."
