It's got to be the Band Aid song, surely. It's quality! Literally written for a crowd to sing.
Do they know it's Chritmas time (from 2:35 onward)
Do they know it's Chritmas time (from 2:35 onward)
Do they know it's Christmas time
Al-der-weir-eld,
Let them know it's Toby time and
Al-der-weir-eld,
Let them know it's Toby time again
Etc
