WATCH: Paul McCartney and James Corden 'Carpool Karaoke' teaser

Watch the teaser clip of James Corden jamming with his dream guest, Paul McCartney for his 'Carpool Karaoke' segment on The Late Late Show.

The teaser starts off with James desperately asking for help, referencing a classic Beatles song, "Help!". He probably also needed someone to help drive the car this time in Liverpool.

The segment will air on Corden's show late this week.
