How is Germany an important setting in the biography, John Lennon?

Lennon and the other Beatles did not enjoy their gigs in Germany because they were forced to play long hours for very little compensation. However, the band's skills at this time were rather raw, and the countless hours that they spent performing dramatically improved their musicianship. The living and playing conditions were as poor as the pay, and the band members were glad to come back home. They eventually returned for a second time but still did not enjoy life in Germany.
