One of the most popular and enduring Christmas songs is the 1984 UK "supergroup" charity single "Do They Know It's Christmas?". You may recognize some of the voices, but who was all involved?

The project was the brainchild of Irish musician Bob Geldof, who called on his famous friends to help the less fortunate in Africa.

Here's a list of who was involved and what parts they sang:

"It's Christmas time, there's no need to be afraid"
"At Christmas time, we let in light and we banish shade"
Paul Young
