Paul McCartney redefined James Corden's Carpool Karaoke segment by taking him on a tour of his native Liverpool, England.

James travelled to his native U.K. record a special edition of The Late Late Show with James Corden earlier this month – and roped in the legendary Beatles musician to help him out.

Calling on Paul,the chat show host quoted The Beatles', singing, "I need somebody, not just anybody. Can you please, please help me" before joining Paul in a rendition of Drive My Car.

Paul directed James to the road he immortalised in song, Penny Lane, whose famous sign they autographed.

They then headed to the rocker's childhood home in Allerton, South Liverpool. While there, Paul explained how he and John Lennon had rehearsed their first Beatles songs in the living room.

"Here, this is where me and John used to come to rehearse or write," he explained. "This was mainly our room. My dad would be in there (the next room) watching telly, we'd be in here, and we'd just written She Loves You, which was a big Beatles hit."

The music legend then went on to demonstrate how he and John had played the track for his dad – but Paul's father was unimpressed as it sounded too American. The elder McCartney suggested his son change the lyrics to 'She Loves You, Yes, Yes, Yes', but Paul refused.

The rocker then explained to James how his mother used to give early Beatles admirers cups of tea, before greeting modern day fans outside his home.

In a radio interview after the visit, Paul explained that he had not set foot in the house for three decades – and that it was only on James' urging he re-entered his old house.

He then took the comedian to Liverpool's famous Philharmonic Dining Rooms pub – where James worked behind the bar serving locals, while Paul performed a set including Love Me Do and Hey Jude.
