Yoko Ono Pleads for "Peace" on John Lennon's 70th Birthday

Nearly thirty years after his death, John Lennon's widow Yoko Ono is remembering the singer on what would have been his 70th birthday.

To commemorate Lennon's special day Oct. 9, Ono posted a YouTube video message (watch above) thanking fans for their support over the years.

"[John] had a very painful childhood, but he managed to turn his pain around to give the world many beautiful songs and important messages which changed our heads and the way of our lives," Ono, 77, says.

"I know John wasn't expecting so much love to come from [the fans], but he would have been very happy to know it. Thank you. May all of us learn to heal ourselves and learn to love each other in peace. I love you," Ono says, signing off as Lennon's "Imagine" plays in the background.

The Beatles singer was murdered outside his New York City home in 1980 by Mark Chapman, who is still imprisoned for the crime.
