That isn't actually meant to be played on a guitar (even assuming I transcribed all the harmonies right!) It's just that I don't know how to represent part music in ABC other than by writing out each part separately in the fashion of the middle ages and renaissance. Instead of that, I have tried to represent B's harmonization by means of formal guitar chords.

If I were actually intabulating to the guitar, I would probably end up with something that had far fewer chord changes.
