I am looking for the proper words and artist for a ditty that goes something like this:

If I was a whale in the sea,
If I was a whale in the deep blue sea
with no mother or father to play with me
I'd feel so sad and I'd be so mad
If I was a whale in the sea.

I think that it was Country Joe or something like that, but I can't locate it. Thanks, on behalf of my first graders. Lucius
