Former Beatle Paul McCartney will be the guest on James Corden’s next instalment of ‘Carpool Karaoke’.

Earlier this week Far Out reported that McCartney returned to Liverpool to surprise fans by playing a secret gig in the Philharmonic pub. The skit will see the two of them going on a tour around Liverpool.

Now, it has been confirmed that the trip was in conjunction with Corden’s popular feature by city tour guide Jackie Spencer, who told Variety: “We’d had a lovely morning. I had four people with me, from Washington State and California, and we were finishing the tour by the new statues.

“There was a couple of paparazzi around and we said to one of them, ‘Who’s the celebrity in town?’ We’d heard rumours but nobody would tell us. And then this guy said, ‘Well, I’ll tell you one of them: It’s James Corden. He’s with somebody else and they’re in that car over there.’

“And the next minute this black car pulls up and both Paul McCartney and James Corden get out of it!”

Apparently, McCartney was unaware that the programme would be filmed in Liverpool: “He just walked to us as we were taking the pictures. About 30-40 people were around, maybe. And he just stood and got pictures with everybody at the statue. He stood by himself,” she continued.

“He was being really nice to everybody. He was backing people in so they could get pictures with him. He and James Corden were taking selfies. And they just walked back, got in the car and disappeared off and went ’round Liverpool. It was fabulous.”
