The world famous Cavern Club on Mathew Street, Liverpool, celebrated 50 years to the day since The Fab Four first played there on 9th February 1961.
People from all over the world sang and danced to the sounds of the famous scousers, as they marked half a century since the leather-clad, cuban-heeled youngsters took to the stage.
Tribute act The Mersey Beatles, one of the finest around, thrilled the audience with a live set that included all the classics from She Loves You to Ticket to Ride.
The original line-up included Paul McCartney, John Lennon, George Harrison and Pete Best, who wasn't replaced by Ringo Starr until 1963.
The original venue was demolished in the 1970's to make way for a car park. Fans from around the world still flock to the refurbished Cavern Club to pay homage to their heroes.
The Beatles went on to play at The Cavern 292 times before they went on to rule the world.
The city is planning a "ceiling of light" across the street, dubbed 'Lucy in the Sky With Diamonds', to mark the anniversary.
