Kenny Chesney turned the Big 4-0 Wednesday night and took time out to party with 200 of his closest friends. It was a star-studded night at the hot Nashville nightspot Cabana. A note on the door of Cabana simply said "Back room closed for private party" but gave no indication of the country star and the rest of the star-power inside.

Rockabilly hillbilly Jason D. Williams provided the entertainment for the party goers. At one point in the evening he handed the microphone over to the birthday boy to perform a wild rendition of "I'll Fly Away" with back-up singers Faith Hill and Kellie Pickler.
