I just played it in Vancouver not too long ago. I don’t think I kept my copies of the parts, or i would look it up, but I don’t remember it being too difficult, though there’s some wild counting in one piece. You get a click-track, which is enormously helpful. Do you have your parts yet? You will want to have a look at them beforehand. There are lots of really exposed bits.
Yes, we played the Fairy Fountain, and the harps are very prominent in it, but not totally solo.
Someone in the audience recorded us and put it on Youtube. You can find it by going to the search engine and typing in “Zelda Vancouver Fairy Fountain”.
