How many stars can you spot in BBC's Beach Boys tribute?

If you like the Beach Boys, then boy do we have a treat for you.

BBC Music organized a cover performance of "God Only Knows" off 1966's "Pet Sounds." But this isn't just a cover, BBC managed to get dozens -- literally dozens -- of musicians under one roof for this performance. The roster is pretty incredible.

Cameos include Lorde, One Direction, Chris Martin and Sam Smith, along with Elton John rocking a suit with live butterflies on it. They're all on a set piece that looks like something out of "Oz: The Great and The Powerful."
