On Tuesday, the 40 th anniversary of John Lennon’s death, his former bandmates Paul McCartney and Ringo Starr as well as his wife Yoko and other family members took to social media to share messages in remembrance of the great singer and songwriter. Lennon died on Dec. 8, 1980, after being fatally shot in from of his New York City home. He was only 40 years old.

“A sad sad day but remembering my friend John with the great joy he brought to the world,” wrote McCartney, who met Lennon when he was 14 years old. “I will always be proud and happy to have known and worked with this incredible Scouser.”

Starr shared a message of “peace and love” for Lennon, also making a request directed to a wide-scale audience. “I’m asking every music radio station in the world sometimes today play ‘Strawberry Fields Forever,” he posted.

The request references one of the band’s 1967 tracks. It was written by Lennon based on memories surrounding Strawberry Field, a Salvation Army children’s home with a garden he used to play in.

Yoko Ono, Lennon’s wife from 1969 until the time of his death, used the occasion to reflect on the cause of her loss. “The death of a loved one is a hollowing experience,” she wrote, adding hashtags from #gunsafety to #guncontrolnow.

She also shared a statistic stating that in the 40 years since Lennon’s death at the hands of a firearm, 1,436,000 others have died from gun violence in the U.S.

Both of Lennon’s children, Sean and Julian, also shared posts on social media Tuesday. Both shared old photos of their father.
