Cee-Lo Green Changes Lyrics to “Imagine”

Here is the video The Rob and Kat Mykals were just talking about on the radio.  On NBC's New Year's Eve show Cee-Lo Green covered John Lennon's "Imagine" but changes the lyric "And no religion, too" to "All religions true."  Many people are outraged.

Do you think it was in bad taste to change the line?
