"Imagine"... one of the greatest songs ever!

I love the song "Imagine" by John Lennon.  I've always loved the lyrics to the song, especially how simple (yet profound) they are.  The music is also very beautiful. It compliments the lyrics perfectly.  It's one of the first songs I learned to play on the guitar when I was a kid.  In my opinion, "Imagine" is one of the greatest songs ever written!! :)
