Well, in a sense, you haven't managed to localise the complications
because the lyrics are stuffed with redundant associatedVoices when
reused elsewhere.

Where the differences are this minor (same syllable count, and
mixed music that's easily distiguished), I would put all the
complication where it's unavoidable: in the notes.

versions, musicA and musicIII, each for one rhythm. The words

to the appropriate music.

Of course, you can break up the music into several variables
from which you assemble the different versions, in order to
localise the variation and make it easier to maintain.

Cheers,
David.
