Signed to the RCA Victor label in 1949, RCA's country A&R man Steve Sholes suggested they switch their comedy to singing parodies of country and pop hits. Most were penned by Burns, the humorist of the pair. Their parody of "Baby It's Cold Outside", as recorded with June Carter, became a hit. The song's composer, Frank Loesser, gave them permission to parody the tune with the condition that the label read, "With apologies to Frank Loesser". It led to a spot on WLS-AM in Chicago in 1950, a tour with bandleader Spike Jones and an uncredited appearance on his recording of Pal-Yat-Chee, and a number of successful albums. They also served as backup musicians on a number of late 1940s and early 1950s RCA Victor recordings by Chet Atkins and on many other RCA country sessions in Chicago and Nashville. Atkins was married to Burns' wife's sister.
