"Besides being a touring comedy team they were noted as seasoned Nashville session musicians. In other words they played on a lot of albums backing up various famous musicians. They were not always credited on the records, and they were paid a set fee for their work. They had their first break as teenagers playing on the Renfro Valley Barn Dance. A locally produced radio show in Tennessee (USA). This lasted until around 1938.
When World War II began the budding stars split up. Homer served in European theater of Operation and as Jethro put it "He was the unsung hero of the Pacific. They wouldn't let me sing!"
After the war the two regrouped and took jobs with Spike Jones. They toured briefly but then got a gig as regulars on the Chicago National Barn Dance as well as regular spots on Don McNeil's Breakfast Club. Both radio programs were based in Chicago. Homer & Jethro were to settle in Chicago and remain even after becoming a national success.They recorded a record or two on the King label circa 1946-48 and then Were Signed by Steve Sholes to RCA in 1948.
Their routine had always been deadpan parodies of popular songs. (sort of a precursor to Weird Al Yankovich) However, they were both first rate musicians and this is why their parodies songs were always popular. They had a number 2 country hit with How Much Is That Hound Dog In The Winder and number 14 with the Parody, Battle of Kookamonga (take off of Horton's Classic Battle of New Orleans)"
