Oops! Sorry about the ghost post above, I hit enter by mistake!
I just heard this song on an XM broadcast of one of Bob Hope's Pepsodent shows, and I recognized it as a melody I'd heard (and had stuck in my head every so often!) during a kitchen scene in 'A Christmas Story'... it's an instrumental version, playing in the background on the radio. I'd never heard it anywhere before that.
Funny, A Christmas Story is supposed to take place in 1939 or '40 (see the Wizard of Oz emphasis of the Christmas Parade scene) but this song is from '41?
