Marc Riley's Musical Time Machine. This week Marc transports us back into a different era... the start of the pop revolution when Beatlemania was about to take over the world. It's March 1964 and Bill Grundy interviews the '5th Beatle', manager Brian Epstein for his regional radio programme Frankly Speaking. We revisit the BBC's archives and hear Epstein speak candidly about how and when he discovered the Beatles and what it was like seeing them perform for the first time. He reveals his role in their image change, just exactly what it is a manager does and his theories on why they'd go on to be a success in America. Plus Brian tells us how he reacted when Paul turned up late for their first meeting. First broadcast in 2009.
