It's from Harry Potter (maybe he just also used it there )! We play Harry Potter in my band now, and I did play it. I don't think it's that hard. You just have to practise It's from "Quidditch". It's such a good piece

Well- I play that in my part of harry potter as well. And the thing from E.T. is then used in "Quidditch". (I kind of know, when I have played it )
