“‘God Only Knows’ is one of the few songs that reduces me to tears every time I hear it. It’s really just a love song, but it’s brilliantly done. It shows the genius of Brian. I’ve actually performed it with him, and I’m afraid to say that during the soundcheck, I broke down. It was just too much to stand there, singing this song that does my head in, and to stand there singing it with Brian.”
– Paul McCartney
