I also found this reference to a song called Fairyland Of Love by "Betty Jo." [Betty Jo Catlett]

A web page about country singer Big Bill Lister mentions a Betty Jo Catlett who sang with a western swing band called the Texas Top Hands around 1947.

There is also a Betty Jo Catlett Watson, from Texas, who has been posting at this Catlett genealogy web page. Don't know if it's the same person, but you could ask.
