London  - Sir Paul McCartney has turned back the clock almost half a century to return to the venue where the Beatles performed their last concert - as he was reunited with his younger self.

The 72-year-old musician performed at San Francisco’s Candlestick Park while fans saw a previously unseen image of the Fab Four, from their 1966 gig at the stadium, beamed on to a screen behind him.

The picture, which shows the band walking across the pitch flanked by police to ensure their safety, was screened as Sir Paul performed Little Richard’s Long Tall Sally, which was the final song the band performed in its entirety at their final show. His concert last night (August 15) - in front of 50,000 fans - was part of his Out There Tour and marked the last concert at the venue.

The image shown on screen was taken by the late Jim Marshall, who was the only photographer given unlimited access to the concert on August 29 1966.
