Brad Paisley's new album,"This Is Country Music" will be in stores on May 24th and he has a lot of guests on it.
Carrie Underwood, Blake Shelton and movie icon Clint Eastwood. Hold on now. Eastwood doesn't sing on the album.
According to Paisley, there's, what he describes as, an epic, movie sounding western. Brad is friends with Clint and his wife Dina and emailed Dina and asked if Clint whistles. She checked and wrote back and said that he does and he'd love to.
So they went into the studio and Eastwood whistled to the track. Paisley said, "If you're gonna have a western, have the coolest cowboy of all time whistle on the thing".
