Music Lyrics: Lyrics Analysis

The song I wish to discuss is Imagine by John Lennon.  The some was written for the album of the same name in 1971.  The song discuss a world without religion, countries, heaven, hell, and no possessions.  It is essentially a plea by Lennon for people to let go of that which divide people and to live as brothers and sisters in humanity.  Lennon, a known pacifist, is promoting a peaceful world with no strife.  Sometimes when this song is covered, the person covering it will change the lyric "and no religion too" to "one religion too' or something similar.  Beyond the lyrics, the piano rift that plays through the whole song is beautiful.  This song though is extremely sad for me to watch and/or listen to.  I find it very depressing and saddening that a man for peace and tranquility would be shot.  I suggest to everyone to go to youtube and search Imagine and watch the first video that pops up.  The song and the video are amazing.
