So basically, for those that haven't seen it, this is a joke score. It's not meant to be played, since it's mostly non-sensicle. But it's funny to read, and there's always a new joke to find.
You can see the Faerie's Aire score here.
If you want to know what the first part sounds like, I 'played' this in a short realization of the Faerie's Aire and Death Waltz. It's piano only, and there might be a couple of wrong notes, but I think it's more accurate that any that have so far been done. i.e. none!
FYI, it took about 3 hours until to get this far, at which point the boredom I felt at the beginning seem productive, so I went to bed...
