Come to think of it, everyone involved has just a small part, but collectively it's an amazing cover of the Beach Boys classic. Among the talented stars involved: Lorde, Sam Smith, Coldplay, Dave Grohl, Pharrell Williams, Florence Welch, Kylie Minogue, Elton John, Stevie Wonder, Florence Welch, Brian Wilson and many more.
The celebs are backed by the BBC Concert Orchestra and proceeds from the charity single's sale will go to the BBC Children in Need campaign.
Beach Boy Brian Wilson told The Guardian: "All of the artists did such a beautiful job, I can't thank them enough. I'm just honored that 'God Only Knows' was chosen. 'God Only Knows' is a very special song. An extremely spiritual song and one of the best I've ever written."
