Speaking as an ex-United Church member (ex only 'cause I live in Wales now) I'd be really interested in hearing more about this.

I think one is ... um...Four Fields? The other one won't make any sense if I just translate the title. The chorus roughly translates: It's quiet now in Esgair Llyn (name of farm) where once I learned to sing the world's song ...
