My mother used to sing about this same subject but all I
can remember goes like this or sort of like this:

The little dutch boy. the little dutch girl
were playing down along the brookside
La la la, la la la la Jack and Jill
Heard it form the little brook that couldn't keep still
La la la he kissed her.
La la la la la la la la
la la la he kissed her.
la la la la la.

I would sure like to know more of this little song.
