On Nightwish's latest album "Endless form most beautiful" there is a song that has some voice over passages and when I first heard it I though: Hey, that guy sounds like Richard Dawkins. Several months pass until I realize that the song is called "The greatest show on Earth". Wait a minute. A quick google search later it is confirmed that it actually is Dawkins.
Dawkins makes his first appearance at ~5:20.
