Hi, sfgas-
Open Mike(in Chico) posted part of the song here (click). I've heard several versions, all more-or-less the same. Here's one:

Fried Ham

Fried ham, fried ham, cheese and baloney;
After the macaroni, we'll have onions, and pickles, and olives, and pretzels;
Then we'll have some more fried ham, fried ham...

(repeat, incessantly, changing volume and using various accents and speeds)
