Here's the video of Cee-Lo Green doing a controversial cover version of John Lennon's "Imagine" at the climax of NBC's New Year's Eve New Year's Eve. Not the worst performance from Cee-Lo, though there were some spotty moments on the high notes. But the rendition offended Lennon fans by changing one of the song's key lyrics, when he switched "and no religion too" to "and all religion is true." I have to agree it was a bad idea for Cee-Lo to edit Lennon's words here, even if some of the backlash has been over the top. I understand he may have had good intentions, but in this instance he really should've just let it be, as it were.
