On what would have been the couple’s 44th wedding anniversary, 79-year-old Yoko Ono tweeted the image in several posts and called for an end to gun violence. She said: “Over 1,057,000 people have been killed by guns in the USA since John Lennon was shot and killed on 8 Dec 1980. 31,537 people are killed by guns in the USA every year. We are turning this beautiful country into war zone. Together, let’s bring back America, the green land of peace. The death of a loved one is a hollowing experience. After 33 years our son Sean and I still miss him. Yoko Ono Lennon.” Picture: Universal News And Sport (Scotland) March 21 March 2013.
