Petty is also known for his brief attempts as a professional country musician. He was signed to a record contract by RCA Records in 1986 and began work on an album with Don Light. His lone single from this period was "The Other Guy", which led to appearances on "Hee Haw" and opening for acts such as Randy Travis and The Oak Ridge Boys. Due to disagreements with his record company and management, Petty later abandoned the album project. Later, Petty recorded a track entitled "Oh King Richard", a tribute to his father Richard written by Rodney Crowell that was released in 1995 as part of a NASCAR-themed country music compilation album.
