"My Son Calls Another Man Daddy," which was issued as the B-side of the #1 single "Long Gone Lonesome Blues," was written by Jewell House, who hosted the Hayloft Jamboree and ran Jewell's Record Shop and Fun House in Texarkana. Like "Wedding Bells" and "I've Just Told Mama Goodbye," the song was filled with the kind of sentimentality that had made Roy Acuff, one of Hank's biggest musical influences, so popular in the South. The song expresses the thoughts of a jailed man who loses his son, a traditional theme in country music. Williams attempted to record the song on March 2, 1949 in Nashville but this version was deemed unsatisfactory. He cut the song again on January 9, 1950 with backing from Jerry Rivers (fiddle), Don Helms (steel guitar), Bob McNett (lead guitar), Jack Shook (rhythm guitar), and Ernie Newton (bass) at Castle Studio in Nashville with Fred Rose producing. It climbed to #9 on the country singles chart.

Charlie Pride covered the song on his 1980 album There's a Little Bit of Hank in Me. David Allan Coe cut the song for his 1997 LP The Ghost of Hank Williams. Willie Nelson also recorded a version of the song.
