Paul McCartney, former member of the legendary band The Beatles, has recently spoken about the time he spent in a Japanese jail.

The musician was arrested in 1980 at Tokyo airport after marijuana was found in his suitcase.

In a previously unseen segment of his Carpool Karaoke appearance, McCartney discussed the incident with host James Corden.

The segment was part of a one-hour special called Carpool Karaoke: When Corden Met McCartney Live From Liverpool, which aired in the US on August 20.

In the segment, McCartney can be heard saying, “I still am hazy as to how that happened but it did. I had some marijuana in my suitcase and I ended up in jail [for] nine days. Scary!”

McCartney also revealed that his sentence could have been much harsher if it weren’t for his celebrity status.

“The guy goes, ‘Oh! [makes incoherent sound],'” McCartney began. “I said, ‘Well, what did he say?’ He says, ‘Seven years hard labour.’ And actually, that was the sentence for what I’d done.”

Despite the seriousness of the situation, McCartney also shared a lighter memory from his time in the Japanese jail. On his last day in the prison, he discussed how the prisoners were required to share a communal bath.

McCartney joked, “By the end, I was like, ‘Come on! In for a penny. I’m going in with the boys.’ So we all went in there and it was fun, y’know, being in the tub with all these Japanese guys.”

In addition to sharing his experiences on Carpool Karaoke, McCartney has also been spotted in Liverpool recently, sparking speculation that he may be filming a new music video.

Film crews were seen near McCartney’s childhood home in the Garston area of the city, though no further details have been confirmed.

This is not the first time McCartney has returned to Liverpool this summer.

In addition to filming his Carpool Karaoke segment, he also participated in a Q&A with Jarvis Cocker at the Liverpool Institute of Performing Arts and made a surprise appearance at the Cavern Club.

Born in 1942 in Liverpool, England, McCartney rose to fame as a member of The Beatles alongside John Lennon, George Harrison, and Ringo Starr.

The band is widely regarded as one of the most influential and successful musical acts of all time, with hits such as “Love Me Do,” “Help!,” and “Hey Jude” solidifying their place in music history.

After The Beatles disbanded in 1970, McCartney continued to have a successful career as a solo artist and collaborator with other musicians.

He has been inducted into the Rock and Roll Hall of Fame twice, once as a member of The Beatles and again as a solo artist.
