Yoko Ono will be on the island of Videy in Reykjavik, Iceland today (Tuesday) for the annual lighting of the Imagine Peace Tower in honor of her late husband, John Lennon, who would have been 73 today. She will light it at 4 p.m. ET, which is 8 p.m. in Iceland. You can check out the tower, which is a beam of light shooting straight up into the sky, tonight through December 8th, the day Lennon was killed in New York City, at ImaginePeaceTower.com.

The graffiti has been removed from John Lennon's star on the Hollywood Walk of Fame in time for his fans to gather there for his birthday.
