When Roberts returned from service, he resumed his spot with the Down Homers relieving Haley. In the early 2000s, a set of 1946 radio recordings by the Down Homers were discovered and Haley is named and performs the solo number "She Taught Me to Yodel." Roberts signed a recording contract with Coral Records in 1949, a division of Decca. His first release "I Never See Maggie Alone" was an immediate hit. It sold a million copies.
