Sorry to make redundant posts, but
I am trying to get my finger
on the pulse of this creature.

Barbara's Whiz-Fish MIDI is part C.

Joe Offer's transcription MIDI of the
SongFest book version, is melody parts B and C.

And neither MIDI file has got the
Part A melody which is documented in
Yale Melodies
on page 66 and concludes in the first half of page 67.
