AceShowbiz - Paul McCartney's recent Carpool Karaoke segment on funnyman James Corden's U.S. late-night show is to be expanded for a TV special.

The skit, which was shot in the Beatles star's native Liverpool and appeared on The Late Late Show in June, has been expanded into an hour-long episode, titled Carpool Karaoke: When Corden Met McCartney Live From Liverpool, and it is set to air in the U.S. on 20 August.

The show will feature unseen footage from McCartney's appearance in the skit, which was shot while Corden's show was taped at Central Hall Westminster in London.

During the filming, Corden and McCartney paid a visit to the former Beatles star's childhood home, as well as notable places mentioned in the band's hit Penny Lane. The rocker also thrilled locals by staging an intimate gig in a city pub.

"We were overwhelmed by the response to our Carpool Karaoke with Paul McCartney. We loved making it and knew we had something special, but it was so wonderful for us to see how many people watched and enjoyed it," said Ben Winston, executive producer of The Late Late Show in a press release. "I think it resonated with people as Paul’s music speaks to every generation, young and old, especially today.

"The message in the music is as relevant now as it has ever been. After the shoot, while we sat in the edit, we had to cut so much we loved for time. Not only did Paul do a concert in that Liverpool pub, but James and he discussed so much in the car. We are so delighted CBS has given us this primetime special to make an hour-long version of this Carpool Karaoke. Now everyone can see the joy of that concert and more of their chat."
