How the heck does one remember something from almost 50 years ago?? I think as kids, we treasured the hilarity and wittiness of both the words and the accompanying artwork, and set to music, it somehow remains intact. Can still visualize some of the funny art, too. I recall one more to share:

To the tune of the "Notre Dame Fight Song"

Cheer, cheer for our charge accounts.
We run up bills in mammoth amounts.
Freezers, sports cars, TV sets.
Each one keeps bringing brand new debts.
What though the bills be great or small?
We can't pay one, so why pay at all?
We will live in comfort while we're heading towards bankruptcy!
