Lee Ann Womack will judge a singing contest this weekend between football greats Terry Bradshaw and Peyton Manning on Fox Sports' Fox NFL Sunday. Bradshaw recorded a duet with Glen Campbell for an NFL country CD, and Manning sang with friend and fellow Tennessean Kenny Chesney on another volume of the series. Fox Sports is sending a crew to Womack's show in Hanford, Calif., to tape her comments. The segment will be a part of Bradshaw's pre-game interview with Manning. Womack also is set to headline the seventh annual Knock Out Abuse Against Women fundraiser Wednesday (Nov. 2) in Washington, D.C.
