You might also find it useful if you can grab a Soundtracker module of the song - if one exists... Then you'll be able to locate the voice containing the melody and the notes there will be shown as A to F.
All I can find with a quick Google is a SID version (which won't help you)
on this page.
- Ali
EDIT: There's a MIDI version on
this page - you could grab that and "dissect" it with some MIDI sequencer software...
