There are several still kicking around obscure corners of my brain, occasionally sneaking into consciousness, even though the products they promoted are either off the market or deep in obscurity.
These relate to growing up in the New York area:
Castro Convertibles. As I remember, these were convertible sofa-beds advertised heavily in the 1960s and apparently even earlier.
*Who’s the first to conquer living space
It’s in-con-tra-vertible
That the first to conquer living space
Is the Castro Convertible
Who conquers space with fine design
who saves you money all the time
who’s tops in the convertible line
Cas-tro convertible!*
I never bought one of these or knew anyone who did. They seem to have been to the '60s what futons were in the '90s.
Then there was Dorman’s Endeco Cheese, a truly oddly named product promoted via lots of radio ads. The jingle’s lyrics were more annoying than memorable, and included the claim that “we make cheese the old-fashioned way”, which I imagine involved a large vat in Passaic, New Jersey. Never ate the stuff.
Lastly there was Rheingold beer, which I seem to remember sponsored the Mets when they were awful, and had a jingle set to a (previously) obscure classical waltz:
My beer is Rheingold, the dry beer
I drink Rheingold whenever I buy beer
Rheingold’s taste ain’t effete
Smells like old stinky feet
Pabst and Schlitz can’t compete
With my beer!
Or something like that. Rheingold went bust after awhile; last I heard it had been reincarnated as a microbrewery beer under new ownership. I’ve never tried either the old or new Rheingold.
Other product jingles you can’t delete from your memory files, no matter how you try?
