If you’re going to cover a song, then cover the song. Sure it’s fine to change the melody, but only an egocentric nut would take one of the most famous songs ever written and completely change its meaning by altering the lyrics. Cee Lo Green sang John Lennon’s Imagine on New Year’s Eve and he changed “Nothing to kill or die for, And no religion too” to “Nothing to kill or die for, And all religion’s true.” When asked about the controversy, Green said that his choice was “done out of love and out of peace and unity and tolerance and acceptance and all those many wonderful things that seem cliche and a little bit cheesy. You may say I’m a dreamer, but I’m not the only one.” It’s always the angry dudes that preach “peace and unity.” Only someone with internal rage would mess with John Lennon lyrics.
