Thanks to the suggestion of purplepiano and gnimmel, I have started using a musical markup program called LilyPond. I've used it to transcribe some of the song about Belflor.
libellum, the top stave shows the kazoo and sax line. Pick whichever part seems more saxophonic to you. smhwpf, can you read music? If so, can you sing this?
There will be complete scores available eventually. randomchris and purplepiano, would you prefer full stave piano music or shall I give you chords and let you improvise something rockin'?
