Paul McCartney returns to his roots with free gig in Liverpool's Cavern Club

Sir Paul McCartney will return to where it all began when he performs at the Cavern Club in a free gig in his home city today.

The Beatles legend will take to the stage in the famous venue on Mathew Street in Liverpool, at 2pm.

Fans will be able to claim free tickets from the box office at Liverpool's Echo Arena from 10am.

Organisers have warned space is extremely limited and tickets will be allocated on a first come, first served basis to those who turn up in person.

The Cavern Club is credited as the birthplace of the Fab Four, who played there in their early years.

Sir Paul had hinted at this secret performance during an interview with Pulp frontman Jarvis Cocker, who was hosting the event: "We are playing the Echo Arena in December but the thing is we also have, tomorrow, we have a little secret gig somewhere in Liverpool."
