This song has a special memory for me too. Every year at Christmas Eve service, just before midnight, the church lights went completely out, and the church choir (in which my whole family sang) entered the church slowly down every aisle, carrying candles and singing "Stille Nacht". We all reached the front by the end of the second verse, and blew the candles out. Pitch black... Silence... Then all at once a huge organ chord, the choir broke into a rousing "Break Forth O' Beauteous Heav'nly Light" (a Bach cantata, I believe), and all the church lights came on at once. So theatrical!

It still makes my eyes tear up every time I remember it.
