Yesterday, March 20, would have been the 44th wedding anniversary of Yoko Ono and John Lennon -- had he not been shot and killed in 1980 by a lunatic fan.

(Like Paul McCartney, we refuse to mention Lennon's killer by name.)

In commemoration of her fallen husband, the now 80-year-old Ono tweeted a photo of his bloodied glasses (which originally appeared on the cover of her 1981 album 'Season of Glass') along with a statistic about gun violence to bring attention to the problem.

Yoko tweeted the picture four different times throughout the day with different messages, statistics and even a heartbreaking reminder that after 33 years, she and her son Sean still miss John every day.

Ono also posted a link to several
photos of her and Lennon's 1969 wedding, after which they
spent their honeymoon in Amsterdam campaigning for peace.
