A musical about the U1 U-Bahn line, which would go on to become world famous, premieres in the Grips Theatre in 1986. The play is all about life in West Berlin. At the time, the U1 line ran from Ruhleben in Spandau to Schlesisches Tor in Kreuzberg. That meant it traversed the whole of West Berlin and cut a cross-section through the many layers of the city’s society. The show turned out to be a huge success for the Grips Theatre.
