[78-L] Name that tune

[simmonssomer]

Goofing around on the internet I ran into a Washington state station playing 
all sorts of music.
My attention picked up when Tommy Dorsey played the familiar trombone intro 
to "Once In A While."
However..when Jack Leonard and the Thre Esquires began to sing the lyrics 
were "Dancing With You."
The tune was unmistakeably "Once In A While"
Circa Nov. '36 to Jan. '37.
No sign of it in Kinkle or any Rust.
Que paso? Who and why were those lyrics changed. Was the song originally 
called "Dancing With You?"
If so, why is that recording not listed anywhere?
