a lu is a lu

Tonight I saw a commercial for these cookie things called "LUs." It reminded me of an advertisement song from my childhood about lus. I started singing it and andy said that he had never heard it! I couldn't believe it, as I knew it by heart. So, I of course googled it, and to my chagrin - no results?! impossible!
Here is the song, as I remember it:
Well a cookie is a cookie and a lu is a lu
Both are great but one is tooooooo
Good to be a cookie so we call them lus
So please don't call them...
COOKIES!
it's a really catchy song.
I may have to cover it in my next band.
Does anyone else remember it!?
