Music legend Paul McCartney made a surprise appearance at the "March For Our Lives" in New York on Saturday to speak out in support of gun control, telling a CNN reporter that the death of bandmate John Lennon was the inspiration for his attendance.

In an interview with the news network, McCartney said he doesn't know whether meaningful gun control is possible in the United States, but that he hopes America's gun violence epidemic can end.

"You know, I'm like everyone. I don't know [if gun control legislation can be passed]," McCartney said. "But this is what we can do, and I'm here to do it."


"One of my best friends was killed in gun violence right around here," he added, referring to Lennon's murder outside his Manhattan apartment in 1980. "So it's important to me."

Lennon was killed by Mark David Chapman in 1980 outside his home after returning from a studio with his wife, Yoko Ono.

McCartney was one of thousands of people who attended marches against gun violence in all 50 states, Washington D.C., and countries around the world on Saturday to commemorate victims of gun violence and call for tougher gun control measures.

Saturday's marches were attended by numerous celebrities and politicians, while others tweeted support for demonstrators around the country.
