She'd hoped to set a new world record - but the previous one, in which a peace sign was created by over 5000 people, remains. Lennon, who released peace anthem Imagine in 1978, was born on October 9, 1940, and shot dead on December 8, 1980.

Ono told fans: "Thank you for coming today. I really appreciate it. I love you!" She'll mark her late husband's actual birthday in Iceland, where she'll relight the Imagine Peace Tower beacon in his memory. Check out video of the peace sign tribute - here.
