The song "Fifteen Men on a Dead Man's Chest" aka "Yo Ho Ho" aka "Yo, Ho, Ho and a Bottle of Rum" aka "The Derelict", etc., has been discussed elsewhere in Mudcat, for example here. Wikipedia gives a discussion here.

A melody for the song is given in the Digitrad here and also at other sites, for example here. But for the original words that were contained in Robert Louis Stevenson's "Treasure Island", namely

Fifteen men on a dead man's chest
Yo ho ho and a bottle of rum
Drink and the devil had done for the rest
Yo ho ho and a bottle of rum.

(or very close to that), I have a very definite memory of a melody, and it is not the melody found in Digitrad or the other site. Here is the melody I know for it, rendered (however imperfectly) in abc notation. I don't know the key I originally heard it in - I arbitrarily put it in C minor:

X:1
T:Fifteen Men on a Dead Man's Chest
K:Cm
M:4/4
L:1/8
|C2D2E2FF | ^F2G2A2G2 |
c2B2A2GG | FFE2D2G2 |
C2DDEEF2 | ^F2GGA2G2 |
c2c2c2c | decd2c2||

If you copy and paste these lines (starting with the "X:1" line) into the window at concertina.net, and then click "submit", you can see the dots and play a midi version.

I don't know where I heard this other melody, but it is very likely that I heard it on television, or possibly in the movies.

Is anyone else familiar with this other melody?
