the moment i heard this, i thought, if you follow the timing he sings "once upon the sandwich isles..." you can sing that melody with the rest of the words right through to upon hawaii all in the first line. Drawing out "upon hawaii" and singing it the exact same way they do in BWPS. maybe thats something he remembered in 2004? just start singing the moment the music starts and it works perfectly, isn't rushed and totally in keeping with his descending vocals as per heroes and villains, so it's not even a stretch of an idea that it may have gone like this. of course, who knows?
i think the fact he calls out to van to check and then sings is significant. it's like he's looking for agreement, so strengthens the case to me that he's singing a genuine melody, rather than made up on the spot!?!
That does sound cool, but that would leave us two lines short, as you can easily fit both lines from 2004 into this new melody in the time it takes to sing one line the 2004 way. Correct?
There were vintage lyrics that went unused for this song in 2004 which only strengthens the idea that a melody with more words was an intention.
