Cee Lo Green's small change to the lyrics to John Lennon's song "Imagine" is causing a very big uproar.

Charged with singing Lennon's famous solo-era tune on NBC's New Year's Eve show shortly before the ball dropped in Times Square , Green changed the lyrics from "Nothing to kill or die for, And no religion too" to "Nothing to kill or die for, And all religion's true."

The change didn't go unnoticed, and to preempt criticism, he soon tweeted, "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."

That did little to comfort angered Lennon fans, who lashed out over Twitter. Watch the performance below (starting around 4:00) and then read the angry exchanges over Twitter.

UPDATE 9:49 AM: All of Green's tweets have been deleted from his account, but can still be seen below.
