John Lennon's peace anthem "Imagine" is a beautiful song which envokes a peaceful world where the major causes of war do not exist. The song lyrics are as follows:

"Imagine there is no hea*ven. It's easy if you try: No he*ll below us, above us only sky.  Imagine all the people...living for today.  Imagine there's no countries.  It isn't hard to do: Nothing to kill or die for, and no relig*ion, too. Imagine all the people... living life in peace. You may say I'm a dreamer. But I'm not the only one.  I hope someday you will join us.  And the world will be as one.  Imagine no possessions ... I wonder if you can: No need for greed or hunger ... A brotherhood of man.  Imagine all the people:  Sharing all the world. You, you may say I'm a dreamer.  But I'm not the only one.  I hope someday you will join us.  And the world will live as one."  :)
