The Wolf Folklore Collection has 15 versions (with audio recordings).

The original "Frog" ("The Marriage of the Frogge and the Mouse") in Melismata (1611) is HERE; Scroll down to "21. It was the Frogge in the well" (pages 37-38).

See also Caldecott's picture book: A frog he would a-wooing go (1883) (without tune).
