I love all the Sax parts for this. Our school is using this as a final feature for the sax upperclassmen who are leaving next year and they all do the whole first page worth of this in solos. It sounds awesome!
PSA my old high school band did an arrangement of this for our marching show in 2014-2015 (look up Cy Ranch marching band Magic - our Area performance in particular)
+nathan T I play the tuba part for my high school (we are well known for our music program) and its very interesting... first page is fairly slow for the tuba part, second you have a few melody/interesting parts... from about 4:41 onwards
