Sean Ono Lennon fears that younger generations could forget about The Beatles

Sean told CBS Sunday Morning: "But obviously the world is also the custodian of his legacy, I would say.

"I'm just doing my best to help make sure that the younger generation doesn't forget about The Beatles and John and Yoko. That's how I look at it."

Asked if he thought if it was "even possible" that the public could forget the Hey Jude band, Lennon said: "I do, actually. And I never did before."

Sean sees it as his duty to protect the legacy of his mother, who is now 92 years of age, and his father - who was murdered at the age of 40 in 1980.

He said: "My parents gave me so much that I think the least I can do to try and support their legacy in my lifetime. I feel like I just owe it to them. It's a personal thing.

"I think The Beatles' music, and John and Yoko's legacy, is something important for the world to kind of cherish and be reminded of. So, that's how I see my job."

Lennon explained that he feels "a lot of pressure" to take over from Yoko as the protector of his father's legacy as his mother has "set a high standard for the way she dealt with my dad's music".

Asked how Yoko is doing, Sean said: "She's good. I mean, you know, she's 92, so she's slowed down a lot, and she's retired. That's why I'm kind of trying to do the work that she used to do.

"That's why I feel a lot of pressure, actually, to do my best, because she set a high standard for the way that she dealt with my dad's music, and The Beatles stuff."

He added: "She's always been very singular. And I think my dad was less so.

"You know, he had Paul (McCartney) to write with, and then he was hoping that my mom would kind of be a writing partner. And I just think it's really funny that, you know, there's probably only one person in the world who would turn down John Lennon as a writing partner, and that's my mom, you know?"
