McCartney guests on Carpool Karaoke

LIVERPOOL — It had been a magical mystery tour as Paul McCartney led James Corden through his hometown of Liverpool during a “Carpool Karaoke “segment on CBS’ “The Late Late Show.”

Thursday’s program wraped up a weeklong stay in London and the 76-year-old Beatles and Wings legend joined Corden for a drive.

In between songs, McCartney autographs the Penny Lane wall and visits his childhood home.

Corden chokes up as McCartney explains how a dream about his late mother led to the lyrics for “Let It Be.”

The pair ends up at a pub, where Corden serves as bartender and encourages patrons to use the jukebox. When one does, a curtain dropped and revealed McCartney on stage with a band. He sings some of his old hits before inviting Corden onstage for “Hey Jude.”

McCartney is scheduled to re-release his 17th solo studio album, “Egypt Station” on Sept. 7. A doublesided single from the album was released this week — “I Don’t Know” and “Come On to Me.”

Production duties are being handled by Greg Kurstin (Adele, Foo Fighters). It’s McCartney’s first album of original material since 2013’s critically-acclaimed “New”.

Details on the album’s content is vague, but it will open and close with instrumentals and include a seven-minute, multi-part suite similar to the second side of “Abbey Road.”
