We sing this at girl scout camp! the lyrics are slightly different:

Anne Marie loves Jean Pierre
It's written on the cafe sidewalks everywhere
Jean Pierre loves Anne Marie
It's written in a heart they carved upon a tree.

Anne Marie, she said one day
"I love you very much so let us run away."
Jean Pierre, he said "Wee, Wee!"
And went to tell his friends "I'm marrying Marie."

They ran off into the park
But they were getting hungry, it was getting dark.
They came back, before to late
For Anne Marie was seven, and Jean Pierre was eight.
Wee!
