Banjo picker from a song by Hee-Haw's Grandpa Jones. He released it as a single in 1961 on Monument Records (b/w "Count Yuor Blessings").
A simple cotton and sugarcane farmer from Alabam(a), Sam runs away from home to join a band. He saves his money and plans to return home and build a mansion for him, his mother, and brother.
This song seems totally unrelated to a much older song of the same title (aka "The Catfish") with different lyrics and a different melody. But perhaps Jones borrowed the name.
