One of the most entertaining things about the early days of recorded jazz music is the clever way musicians worked around the conservative mores of the time. The well-loved etymologist William Safire, in a 2002 article, diligently attempts to decode the playful gibberish sung so beautifully by Nat King Cole in his suggestive tune, “The Frim Fram Sauce,” only to shrug, in the end, and concede that it’s probably “about sex.” You can almost hear the smirk in Cole’s silky smooth voice as he sings:

I don’t want French fried potatoes, red ripe tomatoes
I’m never satisfied.
I want the frim fram sauce
With ussin-fay, with shafafa on the side.
