Has anyone out there heard of Priscilla Herdman? She records childrens songs, many of which are very much in the innocent vain you are discussing here. I wish I knew where I could buy any of her albums, as well as similar stuff. Here is a part of her "Waltzing with bears."

I went up to his room in the middle of the night,
I tiptoed upstairs and I turned on the light,
But when I got there he was nowhere in sight,
And I'm sure Uncle Walter went waltzing that night.

He goes wa wa wa wa wa waltzing with bears
Raggy bears, shaggy bears, baggy bears too
And there's nothing on earth Uncle Walter won't do,
So he can go waltzing, go waltzing with bears.

Etc.
