My 3-year old daughter loves this song, but I don't know all the words. The verses tell the story of the little fishies' trip out to the ocean and back. I am fairly confident this is not in the public domain. I think it was a charted hit in the 1940's (Andrews sisters?). Perhaps someone can finish the lyrics for me. I know the melody.
Down in the meadow in a little fishy pool Lived three little fishies and a mama fishy too Swim, said the mama fishy, swim if you can And they swam, and they swam all over the dam
Boop, boop did-up dad-um wah-dum shoo Boop, boop did-up dad-um wah-dum shoo Boop, boop did-up dad-um wah-dum shoo And they swam, and they swam all over the dam
Thanks
