Guion's "My Cowboy Love-Song" was the theme for the show Cavalcade of Texas, which ran for six months as part of the Texas Centennial Exposition in 1936. His mother died later that year, after which Guion largely retired from public life, moving to an estate that he called "Home on the Range" along Pohopoco Creek in the Poconos in Pennsylvania. He lived here until 1965, when his property was condemned for a dam to be constructed along the creek to create Beltzville Lake.
