Fundraising was also aided by non-USO entertainment groups. Soldier Shows, which troops – often experienced actors and musicians – organized and held their own performances, were common. The army formed a Special Services unit that organized such shows and supervised the USO, and the experience from the Soldier Shows led to Irving Berlin's Broadway show "This Is the Army". Performers and writers from throughout the army were recruited for the production; they remained soldiers and continued drills. Berlin, who had written and produced the similar "Yip, Yip, Yaphank" during World War I, took the entire 165-person cast on tour in Europe in 1942, raising nearly $10 million for the Army Emergency Relief Fund. The following year the show was made into a film by the same title, again starring Ronald Reagan. The "This Is The Army" stage production toured worldwide until it closed in October 1945 in Honolulu.
