Brian Wilson recalled the story of the song, which he wrote the help of his therapist Dr. Eugene Landy: "I was in my piano room, and I was playing 'What The World Needs Now, Is Love, Sweet Love
' and I just went into my own song. I worked very hard to get out of me what was in my heart on that one."
"I called up Dr. Landy and we worded on the lyrics together. I was going for a spiritual, semi-Beach Boy kind of background sound, but more of a Brian Wilson lead vocal thing. 'Love And Mercy' is a real positive vibe; it really is."
