I'm not claiming divinity. I've never claimed purity of soul. I've never claimed to have the answers to life. I only put out songs and answer questions as honestly as I can... But I still believe in peace, love and understanding. - John Lennon 

On the thirty-first anniversary of his death, John Lennon's spirit still soars. 

Now that John's a spirit, he has a different effect on people than when he was alive, said Yoko Ono, 78, to the Vancouver Sun during a call from Tokyo. Tonight, musicians will perform to honor her husband who died many years ago and still lives on as one of the greatest musicians in history. There will also be another tribute concert in New York at (Le) Poisson Rouge featuring Steve Forbert and Marshall Crenshaw. 

Spirits talk on a pure level and don't get distracted by people saying things like, 'That's nice, but why's he wearing that?' she says in a slightly weary voice that betrays the midnight hour. Of course, it would still be better if John was around.

On Dec. 8, 1980, John Lennon was shot and killed outside of his New York City apartment by crazed fan, Mark David Chapman. I thought by killing him, I would acquire his fame, Chapman said to Barbara Walters. 

Lennon was known for his social activism and anti-war rhetoric. He was a praised figure, full of wit and wisdom.  

After the Beatles broke up, and Ono gave birth to their son Sean, Lennon was about to start a new chapter in his life with the 1980 album Double-Fantasy. Alas, he was murdered just weeks after the release.
