Radio song in The Philadelphia Story

Hi folks,

I am looking for a song that plays in the background of the movie "The Philadelphia Story. Katherine Hepburn and Jimmy Stewart are outside dancing after the party (just before they take a swim). They are dancing to a song on a little portable radio. You only hear about 5 bars before the scene cuts.
It is not listed on the soundtracks
I'd appreciate any help!
