When Brad Paisley wrote the instrumental as a western movie-sounding soundtrack on his upcoming album "This Is Country Music", he sought help from a movie icon. Brad has become friends with Clint Eastwood and his wife, Dina, and wanted to include Clint on his album. Eastwood's not really known for a great singing voice. So, Brad called Dina and asked, "Does he whistle?" She said "He'd love to". So, Clint Eastwood went into the studio whistled to the track. Brad says "...you know, it's just little things like that that keep me going. The fun of thinking, 'if you're gonna have a western, have the coolest cowboy of all time whistle on the thing'." Brad's new

album comes out May 24. Here's the title tune from that album as Brad performed it on the CMAs last November.
