1920 to 1940

Berlin returned to Tin Pan Alley after the war and in 1921 created a partnership with Sam Harris to build the Music Box Theater. He maintained an interest in the theater throughout his life, and even in his last years was known to call the Shubert Organization, his partner, to check on the receipts. In its early years, the theater was a showcase for revues by Berlin. As theater owner, producer and composer, he looked after every detail of his shows, from the costumes and sets to the casting and musical arrangements.

According to Berlin biographer David Leopold, the theater, located at 239 West 45th St., was the only Broadway house built to accommodate the works of a songwriter. It was the home of Berlin's Music Box Revue from 1921 to 1925 and As Thousands Cheer in 1933 and today includes an exhibition devoted to Berlin in the lobby.
