Does the original have the line "From Yarmouth down to Scarborough"? Because some lively debate has gone on about that, given that it's not usually considered "down" to go from the one to the other. I read somewhere, in fact, that the original town was Earmouth, in Scotland, which, in dialect, gets a "Y" initial sound, as in "Yearmouth," and the vowel as well gets changed, so that "Earmouth" *sounds* like "Yarmouth."

Can anyone confirm or rebut this suggestion?
