Nashville songwriters create song for boy with two rare disorders WTVF and last updated 2021-05-13 16:48:56-04 NASHVILLE, Tenn. (WTVF) â Six-year-old Nash Hensley, from South Bend, Indiana may be the biggest Kenny Chesney superfan there is. He can name several of his hit songs, and often gives impromptu performances of Chesney's songs for his family. "He just got hooked," said Nash's mom Angela. "I couldn't talk on Bluetooth in my car because all he'd want to do is hear Kenny Chesney." Nash came to know Chesney's music during trips to the doctor's office for tests related to two rare disorders he's had since birth. One, PKU, will put him on a low-protein diet for life. The other, achondroplasia, will keep him from growing to a typical height.
