October 9, 2010 marks the 70th birthday of John Lennon and the world is paying homage. Double Fantasy Stripped Down has been released, radio stations everywhere have programmed John Lennon tributes and even Google is in observance. But perhaps most significantly, Yoko Ono will be in Iceland relighting the Imagine Peace Tower in his honor and she is calling for one million tweets of peace. So if you haven’t already, give John a shout out and Imagine Peace. Please tell your friends and tweet your wishes to: @IPTower. You can also watch the ceremony live at IMAGINEPEACETOWER.com.
