How did you spend your New Year's Eve? Well, if you were Cee Lo Green, you began by royally ticking off John Lennon fans, then briefly apologizing for your transgressions before finally agreeing to disagree.

Yes, Green caught some heat after changing a key line to Lennon's 1971 classic "Imagine" during his performance on NBC's New Year's Eve telecast -- he turned the pointed "And no religion too" into the far more, uh, inclusive "And all religion's true" -- a move that drew criticism from longtime Lennon fans. In a flurry of tweets, they chastised him for everything from messing with the song's true message to causing the late musician to roll over in his grave, a response that had Green on the defensive.

After his performance, he took to his Twitter account to apologize, writing, "Yo I meant no disrespect by changing the lyric guys ... I was trying to say a world where u could believe what u wanted, that's all." Of course, soon after, Green apparently had a change of heart, deleting his mea culpa (and all related tweets), and replacing them with a simple "Happy new year everyone!"

In a follow-up tweet, he took a subtle jab at his detractors, writing that he was currently listening to "We Just Disagree" by Dave Mason, though, in response to a fan's question, he said that his playlist choice had nothing to do with the "Imagine" flap and everything to do with "indifference in general." Of course, Lennon fans will probably be happy to know that, according to Green's latest tweet, he's also been listening to "I'm Only Sleeping," a Beatles track from their seminal Revolver album.

A spokesperson for Green could not be reached for comment on the matter by press time.
