Musician Forum - Band Discussion Board - BandMix

I'm going into my senior year of high school this year, and I really want to leave in a really fun way. So I was looking through some songs that I wanted to suggest to my jazz band director and I came across "Another Day of Sun" from the film La La Land. It just so happens that we also have a fantastic jazz choir, so I pitched the idea for the jazz choir and jazz band join up to perform "Another Day of Sun". Because the film is so new, my director doesn't have any arrangements for us to play, but he was still willing to perform it if I am able to find an arrangement with band and choir. So I'm looking for arrangements online, but the only ones online are only for band or only for choir and nothing for both. I was wondering if anyone has found/access to a jazz band and choir arrangement. Many thanks.
