Of course there is a downside to unbowdlerising. My daughter, who acquired some local notoriety for singing Whip Jamboree when she was 8 (but hit it harder than anyone else locally) refuses to sing the Hogseye Man after I directed her to the thread here on its meaning, and she is no prude.

As to the tune, unfortunately while I can derive pitch from dots I cannot derive timing, but the chords that I use (pitching to Am for convenience) run

(Am)Whip Jambor(C)ee Whip (Am)Jambor(G/D)ee
Ah you (Am)Pigtail (G/D)Sailors (Am)stay away from (G/D)me
(Am)Whip Jambor(C)ee Whip (Am)Jambor(G/D)ee
Ah (Am)Come and get your (G/D)oats my (Am)son
