I was introduced to this song by my boyfriend's mum and decided I want to play it on flute for her. This arrangement is not mine! I found it on Musescore, where it was created by Musescore user mickesv. All I did was transpose it from C Major to G Major (a third upwards) so that it's playable on a usual flute. You could also play it in F Major, but I generally like lower tones, so it's a matter of taste somehow :) Created in Musescore and then imported as .mxl file.
