Dierks Bentley, Martina McBride, Darryl Worley and producer Frank Rogers have recorded a song with campers diagnosed with Williams Syndrome. The session took place Wednesday (June 27) in Nashville at a studio owned by John and Martina McBride. The campers co-wrote the song with Odie Blackmon, Jim Lauderdale and Brice Long earlier this week and will perform it on the Grand Ole Opry on Friday (June 29). The music camp is sponsored by Vanderbilt University. Williams Syndrome is a rare genetic condition that causes medical and developmental problems and is estimated to occur in one in 7,500 births.
