Another one that I knew about but forgot to include in my first post: "Learn to Croon". The first song with that title was written by Harold Arlen & Jack Yellen, originated in the 1931 Broadway musical
You Said It and its chorus begins:
"Learn to croon a sentimental tune,
And end it with the words 'I love you'.
Learn to moan into a megaphone,
and it may be the making of you".
There aren't many versions available online, but I did find the one by Sunny Clapp and his Band o' Sunshine (Vic 22682):

The more famous song of this title originated in the film
College Humor and is most associated with its star, Bing Crosby. It was written by Sam Coslow & Arthur Johnston.
