Lennon made his debut into the music scene when he was just a 5-year-old. He voice can be heard orating on one of the songs fron his mother's 1981 album, "Season of Glass." Since then, he's collaborated with Ono on many of her albums.

At the age of 16, he co-wrote "All I Ever Wanted" for Lenny Kravitz on 1991 the album, "Mama Said."

According to People, Lennon wrote on his SoundCloud page that he co-wrote a song with the late Carrie Fisher in 2017.

Carrie and I wrote this song years ago. When she died I just felt I had to record it. This is only a demo unmixed, we only had a few hours to record it. But the lyrics she wrote with me I think are marvelous.

Carrie and I used to stay up til dawn chatting and pontificating about life. They were my best moments.

On May 21, 2013, McCartney made waves in the music industry with the self-referential debut album aptly titled Me, and subsequently embarked on a U.S. tour.

His latest album, "The Blackberry Train" was released on May 6, 2016.

In addition to carrying on with his father's musical legacy, McCartney also practices Transcendental Meditation.

"Transcendental Meditation plays a big role in my life as it has done for my father and the other Beatles. I meditate regularly—twice a day. ... I find that just 30 minutes of Transcendental Meditation refreshes me as if I had slept a few hours!"

When the BBC asked McCartney what his thoughts were on the prospect of "The Beatles - The Next Generation," with Sean Lennon, Dhani Harrison and Zak Starkey [Ringo Starr's son] in an April 2012 interview, he entertained the idea.

I don't think it's something that Zak wants to do. Maybe Jason [another of Starr's sons and also drummer] would want to do it. I'd be up for it. Sean seemed to be into it, Dhani seemed to be into it. I'd be happy to do it.

It's been six years since that interview and we're still all for it.
