A Canadian dentist who paid $30,000 for John Lennon's rotted tooth wants to use it to clone the late Beatle. He is reported to have said that it would be great to bring back one of rock and roll's greats. But, would it?

If you clone him, he's going to start as a baby and he's not going to have the same influences, experiences, and idols as the original did. Who's to say a happier childhood might lead him to a totally different outcome; he might prefer to be a lawyer or an engineer. Literally millions of differences would exist between the world the original John Lennon grew up in and the one that is reality today. I hope the dentist is unsuccessful in his project; the expectations for the clone would be crushing.
