Atonement soundtrack - organ music

Does anyone know what the organ music was at the end of that wedding in Atonement? It is on track #11 called Come Back.

Can’t help, but I am amazed to see that one of the tracks is called “See you and tea”! :eek:

To be clear to the others who may read this, it is “Cee, You and Tea.” There is a character named Cecelia, Cee for short.

Not just that, but a certain four-letter word has an important part to play in the movie.
