There are different versions of the Froggie song. The one I grew up with was A Frog He Would A-Wooing Go, which is the version with Hi Ho says Raleigh! in it, although I have no idea whether this refers to the unfortunate Sir Walter.

I also like the American version where Miss Mousie tells Froggie, "You ain't no frog, you're a horny toad.":)

Is the Crawdad song the one about "You get a line, and I'll get a pole?" If so, how do you fish for crawdads (ie, crayfish, a kind of tiny, tasteless fresh water lobster) with a line and pole? Up here folks use traps.
