It might just be one of those collective consciousness tune thingies. I'm getting "blow up your TV" or a polka.

Are you hearing,

"Smoke Coca-Cola cigarettes, drink Wrigley's Spearmint beer
Ken-L-Ration dog food keeps your wife's complexion clear
Chew chocolate covered mothballs, they always satisfy
Brush your teeth with Lifebouy Soap and watch the suds go by."

?

Are there oom-pahs involved?
I'm coming real close to thinking of an old march tune, but then, The Chicken Dance pushes it out of the way.
