Pigs. "Singing" Christmas songs. Well, why not? Don Carlos' Singing Dogs' "Jingle Bells" is one of the all-time classic holiday novelties, and the "Jingle Cats" albums did well. So, in 1994, Texas musician Bobby Breaux took advantage of the then-popular potbellied-pigs-as-pets fad to record a short album of sampled pig squeals and grunts set to holiday standards.
The fad didn't last long, as pig owners soon found out that those cute little piglets grew into 200 lb beasts with monster appetites. But at least it inspired this (now out-of-print) CD "The Jingle Bellies."
The Jingle Bellies "Joy To The World" - a more disgusting, almost flatulent version you'll never hear. Which, of course, coming from me is a compliment.
