From the wiki:”Pee Wee King, and most of his group,the Golden West Cowboys, were riding in a limousine in 1946 when he and vocalist Redd Stewart co-wrote the song. They were on their way to a Grand Ole Opry appearance in Nashville when they heard Bill Monroe’s new ‘Kentucky Waltz’ on the radio. Stewart immediately began writing the lyrics on a matchbox while King and the other musicians hummed King’s theme song, ‘No Name Waltz’. King and Stewart presented ‘Tennessee Waltz’ to music publisher Fred Rose the next day. The Golden West Cowboys were not able to record ‘Tennessee Waltz’ until December 1947. Meanwhile, Cowboy Copas, who still occasionally performed with The Golden West Cowboys, recorded the song for King Records just after the Cowboys, with Copas’ version released just prior to that of the Cowboys.
