The tapes were originally described as having been recorded in the spring of 1962, an attempt to pre-date The Beatles' June 1962 contract signing with Parlophone. However, song arrangements and dialogue from the tapes pointed to late December 1962, and a recording date of 31 December 1962 (the group's last day in Hamburg) was commonly cited. Later researchers have proposed that the tapes are from multiple days during the last week of December; Allan Williams (The Beatles' booking agent at the time) recalled that a total of about three hours was recorded over three or four sessions between Christmas and New Year's Day.
