The link, below, is to a recording from January of 1950, by the Kay Kyser Orchestra.
The song, released on Columbia Records, is "Open Door, Open Arms." Its vocals are by Michael Douglas (known years later, when he hosted a television talk show, as Mike Douglas), and my mother, Sue Bennett.
When "Open Door, Open Arms" was recorded, Mr. Douglas was twenty-nine years old. My mother was twenty-one. At the time, they were both singing on Kay Kyser's weekly television show, on NBC.
Mr. Douglas sings for a little more than half of the recording; my mother then sings for the remainder of the song.
As I have noted previously, in this space, it was not uncommon, during this era, for popular songs to be recorded by multiple performers. Other versions of "Open Door, Open Arms" were, for example, released by The Andrews Sisters, with the Lee Gordon Singers (recorded in November 1949); by Jo Stafford and The Starlighters (recorded in December 1949); and by the country singer Cowboy Copas (recorded, as was the Kay Kyser version, in January of 1950).
Here is the Cowboy Copas recording of the song:

In the above video, there are rotating (and repeating) still images; one of the images, of a newspaper's front page, concerns the death of Copas, in the crash of a small plane. The crash occurred in 1963, in a wooded area in Tennessee. All of those on the plane--Copas, singer Patsy Cline, singer Hawkshaw Hawkins, and pilot Randy Hughes--were killed. Randy Hughes was Patsy Cline's manager, and was Cowboy Copas's son-in-law.
