1. The best of them all comes from Flight Of The Conchords
2. Brett Domino's How To Make A Charity Single
3. Not strictly a charity single, but I like Pulp's Bad Cover Version
4. The Simpsons' Sending Our Love Down The Well
5. USA For Africa's We Are The World. Everyone who matters is in this video.
6. Band Aid 20's Do They Know It's Christmas? My secret shame is that this is my favourite version.
