A Heritage Foundation plaque has been unveiled at the London office of Brian Epstein, the man who discovered and managed The Beatles.
The plaque is on the front of Sutherland House, next door to the London Palladium, where Epstein ran his NEMS Enterprise management company.
Actress Vicki Michelle, 80s popstar Adam Ant and actor Andrew Lancel, who will play the music mogul in a production next month, all attended this afternoon's ceremony.
Epstein, who died from an overdose in 1967 aged 32, would have been 80 this year.
A collection of some of the most important pieces relating to George Harrison and the Beatles will go to auction later.
Items including George's Cavern Club and Hamburg era leather jacket are estimated to sell for £90,000 - 120,000 at Bonhams Entertainment Memorabilia sale
The producers of the upcoming West End production, 'Let It Be', are looking for talented musicians to play the parts of Paul, John, George and Ringo on the show, from September 2012. Open auditions are being held at the Gielgud Theatre in London today.
Potential Beatles must be talented musicians capable of performing Beatles hits as part of a live band. The producers also state that a physical resemblance is also desirable.
'Let It Be' will run at the Prince of Wales theatre in London, which was the venue of the Fab Four's gig at the Royal Variety Performance in 1963.
