What an incredible collaboration to help launch the new BBC Music, "an ambitious wave of new programmes, innovative partnerships and ground-breaking music initiatives that amount to the BBC's strongest commitment to music in 30 years," The Guardian reports.

Pharrell, Chris Martin, Sam Smith, Dave Grohl, Sir Elton John, Lorde, One Direction, Kylie Minogue, Stevie Wonder, Florence Welch and more amazing artists come together to sing the Beach Boys classic song "God Only Knows."  Original Beach Boys member, Brian Wilson, makes an epic (and appropriate) appearance in the song as well.By the way, the video was filmed at London's Alexandra Palace, where the BBC's first broadcast occurred nearly 100 years ago.

The song will also be released as a single and benefit the BBC's Children In Need charity.
