Here's the story:

To change those particular words in that song, means that he has no idea what John was singing about in that song. He was singing about us all being free and in peace, with no divisions between us. Religion by its nature creates divisions (no offence intended for any folk out there). Catholics vs protestants.. there's a lot of anti-muslim sentiment creeping in to New Zealand culture due to recent immigration-related initiatives, and there's also the animosity towards say Jehovahs Witnesses and the Brethren. Regardless if you're religious or not, people are going to argue over it til the cows come home.
That's why John was saying, imagine no hell below us, above us only sky. The world would be more united if we had none of the dogma between nations and between individuals. To change those vital words means Cee Lo completely missed the point of it all. He has forfeited the right to sing it, in my opinion. He should stick to judging reality singing shows.
