Though the half-brother of Julian Lennon and Kyoko Cox has mostly kept his personal life private, in late 2025, he spoke with CSB Sunday Morning, where he called himself the custodian of his father's legacy.

“Yeah, technically 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,” he shared.

Sean also expressed his gratitude towards his famous parents as he stated, “My parents gave me so much that I think it's 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.”

Regarding what he views as his parents’ legacy, Sean added, “Peace and love. But it's not just peace and love. It's an attitude towards activism that is done with humor and love.”
