Who Sang "Dan Dan"?

In the 1990s there was a children's singer who sang a song with these lyrics:

Dan Dan Little Dan Little Dan Dan
I'm just a little man
A little man is what I am
Says Dan Dan Little Dan, Little Dan Dan
I'm just a little man
Little Man Dan

You can't get under me
Try if you can
You can't get under me
Cause I'm just a little man
You can't get under me
Try if you can
I'm just a little man
Little Man Dan


There was more, but this is what I remember. Anybody know who sang this? The singer also sang a song about various shapes, such as Bobby Triangle and Mrs. Square.

Might be this song: Doug Barr - Little Dan Dan
However it's from the 80's
