I saw this.
As much as I love what Lennon did musically he was a drug addled dick the majority of his life. He was hooked on smack for years at the end of the Beatles run, he wrote Cold Turkey because he was kicking with Eric Clapton on an international flight to the US for a concert.
I rewatched the Documentary "Lennon in America" a few weeks ago. He was terrible to Yoko and the whole "Long Weekend" period was selfish.
I don't think the world needs another Lennon, the clone's life experiences and motivations will be different. It does not make sense to try to clone anyone and expect the same outcome.
The only useful field where cloning would be a good thing is for the Porn industry. Just think about a stack of just turned legal aged Traci Lord's clones for sale!
