The next episode of James Corden’s 'Carpool Karaoke' is going to be epic, if this teaser trailer is anything to go by.

As the clip for the upcoming segment promises, Corden’s next guest is ‘the best-selling artist of all time’ with ‘over 1 billion worldwide record sales’ as well as 18 Grammys. We had an idea of who it could be – and then there was the big reveal.

Paul McCartney will be the talk show host’s next guest on The Late Late Show next week, when the series returns to London.

The trailer sees Corden call McCartney and quote the Beatles hit song ‘Help!’ as he says: “I need somebody… not just anybody… please, please help me.”

When Paul joins James, the two sing ‘Drive My Car’ from the Beatles’ ‘Rubber Soul’ album.

Along with McCartney, the line-up for Corden’s return to London this week is set to feature Chris Pratt, Damian Lewis, J.J. Abrams, and Ruth Wilson. Other announced guests include Cher, Cate Blanchett, Orlando Bloom, Niall Horan, and the Foo Fighters.

Back in March, Paul McCartney was among a heap of stars including Miley Cyrus, Lady Gaga and Amy Poehler to join the March For Our Lives, which took place in over 300 cities in America and worldwide.
