I have a dim memory of seeing a 1960s comedy/musical in which the song Baby Face was sung. ISTR that the film was set in the '20s. What is the name of the film? (Or am I misremembering?)
That’s it! Didn’t even have to click the link; seeing the name was enough.
Thanks!
Awww, but I coded those links. Can’t you just click on them anyway? Otherwise, why am I here?
Incentive? There’s a lovely Julie Andrews leg cross in the YouTube clip.
Don’t worry. I clicked after I posted. 
For what it’s worth: My research began with the Wiki page for the song. Well, actually a Wiki search for the song title but I did that search fully expecting the song to have its own page. The info that it was used in the film Thoroughly Modern Millie was on the song’s Wiki page.
Ignorance fought. I always wondered where this one came from.
