OK, here's a couple I found that both have "Rubber Blubber Whale" which was written by Si Kahn, of folksinging fame. The first CD is by John McCutcheon, who is an awesome singer and hammered dulcimer player. It's called Howjadoo. The next one is by Charlotte Diamond, and is called Diamonds and Dragons. I don't know anything about her.
You could listen to both and see if anything sounds familiar.
