My girlfriend fished this out of a dusty box on one of the rare occasions that we went to a flea market together some years ago. I think both sides are on “Las Vegas Grind” or some other Crypt compilation.
This is the German pressing from 1966 on Golden 12 records. Pretty strange drawing of Alfred E. Newman on the sleeve. Obviously the artist wasn`t familiar with MAD magazine. “It`s a Gas” is a childish twist song interrupted by burping noises. Must have driven the parents nuts to hear it from their kids rooms over and over again…
(UPDATE o9/04/ 2009: During our recent stay in the US, I found a copy of the issue of MAD magazine that “It´s a Gas” originally appeared in, at a cool new comic book store calleed Desert Island in Brooklyn. The flexible cardboard record was missing, but it would have been much more expensive with it than the 4 dollars I paid. Painted in watercolor by Norman Mingo, the long-time Mad illustrator who invented the image of Alfred E. Newman.)
