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

"One of my best friends was killed in gun violence right around here," he said.

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."

Lorna Mae Johnson, the assitant treasuruer of the Democratic National Committee, posted a brief video of McCartney exhorting people to make use of the electoral franchise.

"Get out and vote out," McCartney said. "You can make the change, it's up to you."
