The popular one at my school was:

Down Down Baby
Down by the rollercoaster
Sweet sweet baby
Mama never let you go
Shimmy shimmy cocoa pop
Shimmy shimmy rah
Shimmy shimmy cocoa pop
Shimmy shimmy rah
I had a boyfriend
A biscuit!
He’s so sweet sweet
A triscuit!
Apples on the table
Peaches on the floor
Step out baby you don’t love me no more
to the front
to the back
to the side side side
to the front
to the back
to the side side side

Funny how ridiculous these are when you’re all grown up!!
