Bruno Koschmider was a German entrepreneur in Hamburg, Germany. He controlled various businesses, such as the Bambi Kino, which was a porn cinema. Allan Williams booked The Beatles (in May 1960) into Koschmider's Indra club.
The Beatles first played at the Indra club - sleeping in small, dirty rooms in the Bambi Kino - and then moved (after the closure of the Indra) to the larger Kaiserkeller In October 1960, they left Koschmider's club and worked at the "Top Ten Club," which was run by Peter Eckhorn. When Paul McCartney and Pete Best went back to the Bambi Kino to get their belongings they found it in almost total darkness. As a snub to Koschmider, they found a condom, attached it to a nail on the concrete wall of their room, and set fire to it. There was no real damage, but Koschmider reported them for attempted arson. McCartney and Best spent three hours in a local jail and were deported, as was George Harrison (for working under the legal age limit).
