John Lennon's widow Yoko Ono will unveil a light tower in Iceland to mark the Beatles legend's 67th birthday next month (Oct07). Ono, 74, will travel to Reykjavik to reveal the Imagine Peace Tower in Reykjavik on 9 October - Lennon's birthday. She revealed she and Lennon spoke about creating a conceptual light sculpture in the 70s. She says, "This is something that we spoke about 40 years ago. Our dream is finally coming true. "He was visualizing then that it would probably become a reality one day." "This is the biggest birthday present I gave to John. He's very, very happy about it, I know." Lennon was shot dead in New York City aged 40 in 1980.
