The period covered by this receipt represents the Beatles' first seven days of a gruelling thirteen-week engagement at the Top Ten Club, and their second professional stint in Hamburg. The hours were long and the salaries 'modest' according to the terms of their agreement with Peter Eckhorn, the club's owner, they were required to perform between 7.00 pm and 2.00 am on Mondays to Fridays, from 7.00 pm to 3.00 am on Saturdays and from 6.00 pm to 1.00 am on Sundays, with a 15-minute break every hour. They also had their all-in accommodation thrown-in ...dingy - old army bunk-beds in the attic four flights above the club..., for 35 DM [£3] each per day. As with their first trip to Hamburg, this second engagement had an enormously beneficial effect on the group's performances and technique. As Mark Lewisohn remarked ...13 weeks at the Top Ten club, playing a staggering total of 503 hours on stage over 92 nights..It was little wonder then that..their [The Beatles] stamina and musical versatility improved dramatically as the visit worn on. When they returned to Liverpool in July they were simply untouchable..
