Beatle Track, but soon realised the club had terrible acoustics. Epstein also hired Beatles secretary Freda Kelly, whose memories of him, the Cavern and the Beatles over the group's duration are detailed in the documentaries noted above and in the 2013 documentary Good Ol' Freda. Dress code Although Epstein had had no prior experience of artist management, he made it clear that he wanted to change the Beatles' early dress-code and attitude on stage, as they wore blue jeans and leather jackets, smoked, ate and swore, stopped and started songs when they felt like it, pretended to hit each other, and turned their backs to the audience.

Another improvement was that the group was now far more organised; having a single concert diary in which to record bookings, rather than using whoever's diary was to hand. Worldwide interest During their "Welcome Home" session at The Cavern in June 1962, The Beatles gave what Wooler described as "one of their finest ever performances", drawing "a feverish reaction" that was equal, Wooler said, to the "Beatlemania" that broke out nationwide a few months later. The Cavern Club's popularity grew; rapidly becoming the most famous club in Britain. The Beatles' press officer, Tony Barrow, wrote a book called On the Scene at the Cavern, using the pseudonym Alistair Griffin. "On the Scene at the Cavern," a book including
