Saville Theatre, Shaftesbury Ave. London
Set to perform live on British television on August 1, their first such appearance in more than a year, the Beatles spent part of this day in private rehearsal on stage at the Saville Theatre, a central London venue leased by brian Epstein's NEMS Enterprises from April 1, 1965 until after his death.
While there, the group also gave two inteviews for BBC radio, principally discussing HELP!, premiered in London just the night before, July 29th. The first interview was with Dibbs Mather, a long and witty conversation which was, most unusually, distributed by the BBC's Transcription Service to the British Council which promoted British culture in foreign countries. Along with disc material, it was packaged simply titled The Beatles, sent to the British Council in New York and dispatched from there to specified US radio stations for local broacast.
The second interview was with British entertainer/comic actor Lance Percival, two minutes of which was broadcast the next day, between 12:00 noon and 12:29 pm, in his Light Programme records show Lance A Gogo.
