all the music, etc had been recorded before hand. jon was laying down the vocals. he started singing, and obviously he got very emotional. they kept recording because thats what he would want. jon is all about raw emotion and showing it how it is. at the very end of the song, after you hear the woman singing over his crying, you can hear him open the door to the studio and leave, because he had to get out of there. it was too much for him.
