Ace Frehley fans are looking forward to his new Origins Vol. 1 covers LP for any number of reasons, but the biggest one might be the fact that the record includes a long-awaited reunion with Frehley's former Kiss bandmate Paul Stanley on a cover of the Free song "Fire and Water."

Rolling Stone is offering an exclusive premiere of the track (which you can listen to above) as well as a look behind the scenes with quotes from Frehley and Stanley about working together again for the first time in more than a decade. Both insist that despite the war of words that's been played out in the press, they've always maintained a friendship; according to Stanley, "People look through the windows and the see mouths move, but they don't hear what's being said."

Recalling the call from Frehley, who asked whether he'd work on the record, Stanley added, "I was happy Ace called me up with this. It's very funny, because on my phone when he called, his name comes up, and it put a smile on my face. Like, I pick up the phone and go, 'Ace Frehley!'"

"I thought Paul did a fabulous vocal on it," said Frehley. "He jumped at the chance to do this because it's something that's outside of Kiss and his character in Kiss, and it gave him a chance to, you know, sing. With Paul, you usually think of him singing in a slightly higher register, and on 'Fire and Water,' he's singing deep from his diaphragm, and it's a real cool vocal. Everyone who's heard it just thinks it's the s---."

Frehley previously released a Slash-assisted cover of Thin Lizzy's "Emerald." Origins Vol. 1 is in stores on April 15.
