So here's the short of it, 
Imagine

And here's the long.

I'm sitting here watching the closing ceremony for the Olympics.

I was out of the room for a bit and came back in to see John Lennon singing Imagine.  I was pretty confused for a couple of seconds there.  It took a little bit for me to realize that it was a video clip of him.

Imagine there's no countries
It isn't hard to do.
Nothing to kill or die for
...
Imagine all the people living life in peace.

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.

O dear, that sounds a bit like a Hippie Peace Freak doesn't it.
I wonder sometimes.....  How many of us would have to want that to make it happen.
