Paul McCartney, citing John Lennon's murder, joins March for Our Lives in New York

Wearing a black T-shirt that read "We can end gun violence," Paul McCartney joined the March for our Lives in New York City Saturday.

The 75-year-old former Beatle and his wife, Nancy, joined a multitude of marchers on the Upper West Side in Manhattan to call for an end to gun violence, in the wake of the Feb. 14 mass shooting in a high school in Parkland, Florida.

“One of my best friends was killed in gun violence right around here," McCartney told a CNN reporter. "So, it's important to me."

McCartney's band-mate and songwriting partner John Lennon was gunned down in December 1980 outside the Dakota apartment building at West 72nd Street and Central Park West.
