Help with moomin music

Hi everyone, I’d like to play this music (linked) from a Moomin episode at my wedding but I’m struggling to find a good quality version. All the info I can find is in Finnish or Japanese, neither of which I speak.

It is either named as hosulin ja sosulin häämarssi or muumimusiikkia 5 and there is partial sheet music here: https://musescore.com/user/27502593/scores/5977001.

I’d love to know if there’s a link to a nice version somewhere, happy to pay for it. Also if anyone knows which episode it’s from that would be great!
