John Lennon is 70.

There's a nice tribute to Lennon in today's Google logo. An animated line drawing, with exactly what you'd expect in the audio track. Must it always be "Imagine"?

Imagine no "Imagine"
What song would they use
For every Lennon tribute
In the annual Lennon news
Imagine all the people
Freed from that old song...

You may say I'm a dreamer
Like some crazy peacenik dove
I hope someday you'll join me
And the new song would be Love.
