Reports say that the sound quality was so bad on the TV footage that an additional taped sound was captured. “Granada sent a sound engineer back to the Cavern just to record audio, which was to be dubbed onto the film.”
The Beatles’ manager Brian Epstein was so impressed with the recording that he asked for five acetate discs to be pressed from the tape to use as promotion. One of these five discs was sold at auction in 1993 for £16,000 to Apple Records, the label set up by The Beatles in 1968.
The tape is to be sold by auctioneer Adam Partridge
