Definitely of limited regional flavour, but I remember something that went a bit like this:

Zero zakus smootcha prockus
Halla ballooza bub
That's the secret password
That we use down at the club.
And zero zakus smootcha prockus
Halla ballooza ban,
Means now you are a member of
KINGs TV club with Stan......and Nomo and.....

I loved Stan Boreson and his wonderful Basset hound, Nomo

And also:

Wunda Wunda is my name
Oh boys and girls
I'm glad you came
We'll have fun as I explain
How to play the Wunda game

Wouldn't get by some censors for small children now, it was way too Harry Potter pagan......the hostess wore a witch's hat and had a wand.
