Hello there fellow tune-smiths. I just downloaded a Holiday 100 playlist and it contains an afro-jazz version of O Holy Night in 12/8 time. I love the rhythm, the chords and the whole feel of the music. The only problem: I cannot for the life of me figure out how the melody of O Holy Night fits in.

Has anyone worked on this? Can you point me to any recordings or give me any tips?
