Can anyone help me find this piano music?

I have a friend that plays what she claims is called “The Most High Rules”. She said she got it from a piano music book of some kind. I really like how it goes and I’ve searched for it on two separate occasions now. Yet, for the life of me, I can’t find any relevant results on the internet. Maybe I’m doing something wrong, maybe it just isn’t online anywhere. Anyway, if anyone could perhaps find it for me or point me in the right direction it would be much appreciated. Any ideas?
