The former Beatle told CNN Saturday that he is participating in the New York March for Our Lives rally to honor his late, former bandmate.

“One of my best friends was killed in gun violence right around here,” McCartney told the news station. “So it’s important to me.”

Lennon was shot to death while walking home near Central Park on Dec. 8, 1980 by Mark David Chapman. Chapman, who pled guilty to second-degree murder, was sentenced to 20-years-to-life. Lennon was 40.
