Panis Angelicus
I know this song was not on the original list. BUT, just listen to this AMAZING recording of my principal from 2000 (?) singing the top line, with the children's choir singing S2 unison. It doesn't get much better than this! I DARE you to listen to this when you have a little time to yourself and not BAWL your eyes out. You can get the music here: Panis Angelicus
