Oh dearie dearie me ...

Barbara's MIDI file sounds to me like

"O! Shades of Isaak Walton! Was that another bite? ... "

as regards the Whiz-Fish sheet music from Yale.
Barbara's MIDI files sounds nothing like
the melody printed out for the opening four lines of each stanza.

We seem to have MIDI files
of bits and pieces of this tune,
and not the whole of the piece.
