While he can always be counted on for 16 solid bars, most people would assume the chances of Wu-Tang Clan's Ghostface Killah appearing on a track with Country crooner Lyle Lovett rank slightly below seeing an ice storm in Hell. But, that's exactly what fans will hear on the title track of the Judd Apatow produced spoof Walk Hard: The Dewey Cox Story.

The biopic parody comes from the same producers of Superbad and The 40 Year Old Virgin, and Ghostface will likely make a brief appearance. The song also features Jewel and Jackson Brown, and is part of an elaborate performance scene at the end of the picture. Walk Hard, and its accompanying soundtrack are not expected to be released until Christmas, but Lovett gave Rolling Stone some details about his work with "Tony Starks."

"It was the first time to meet Ghostface Killah," said Lovett. "It was cool, he's very cool. There's a breakdown in our version, in the middle of it, where Jewel yodels and he raps over that."
