American Atheists President David Silverman wants Cee Lo Green to show just how tolerant he is by singing Imagine using the original lyrics at the largest gathering of non-believers in American history.

On New Year’s Eve, Green performed the song in front of a television audience of over two million but changed the lyrics from “nothing to kill or die for / and no religion too,” to “nothing to kill or die for / and all religion is true.”

Since then, he’s has faced a wave of criticism from fans:

Mr Green swatted off those critical responses left and right on Twitter following, in sometimes similarly obscene rebuttals, but by late Sunday morning he had removed all of the postings. ‘Yo I meant no disrespect by changing the lyric guys! I was trying to say a world were u could believe what u wanted that’s all,’ Mr Green was seen as explaining in a tweet.

On my radio show this morning, Silverman responded. As chair of the March 24 Reason Rally in Washington DC (billed as the largest “atheist event in world history), Silverman invited the singer to attend and perform Imagine for the godless. If Green intended to communicate a message of tolerance as he claims, he can prove it by singing the song as written. Silverman promised to pay Green’s expenses — all he has to do is show up and sing “nothing to kill or die for / and no religion too.” Listen:
