Where Can I Find The Flute Letter Notes To Butterfly Fly Away?

I'm looking for it too. You can use the piano sheet music that you can get on the internet if you are a high enough flute grade, I'm grade 6 now and it is pretty easy with the piano music, but as it is a flute you might need another flautist to play the chords. (: And play it rather fast. :D
