_Source._--Kirkpatrick Sharpe's _Ballad Book_, 1824, slightly
anglicised.
_Parallels._--Mr. Bullen, in his _Lyrics from Elizabethan Song Books_,
p. 202, gives a version, "The Marriage of the Frog and the Mouse," from
T. Ravenscroft's _Melismata_, 1611. The nursery rhyme of the frog who
would a-wooing go is clearly a variant of this, and has thus a sure
pedigree of three hundred years; _cf._ "Frog husband" in my List of
Incidents, or notes to "The Well of the World's End" (No. xli.).
