On this day The Beatles' 56th evening show at the Cavern Club took place. They were on a bill which was headlined by Jim McHarg's Jazzmen.
McHarg was a double bass player who had been the frontman for the Clyde Valley Stompers in the 1950s. He subsequently moved to Canada, but returned to England and formed the Jazzmen.
Overall this was The Beatles' 146th appearance at the underground Mathew Street venue, including their lunchtime shows. The precise number of their Cavern performances is not known, although they played at least 155 lunchtime and 125 evening shows between 9 February 1961 and 3 August 1963.
