Música de siempre is a 1958 film produced by the A.N.D.A. that provided work for hundreds of union members at a time when the Regent of Mexico City Ernesto P. Uruchurtu cracked down on the entertainment business. The film is a combination of acts strung together with a story of a theater janitor, played by the comedian Manuel Valdes, who tries to persuade two film producers to make a movie about music. Among the entertainers he suggests for the movie is Libertad Lamarque, Toña la Negra, Edith Piaf, and nine-year-old Angélica María, along with Altia Michel, German Valdes, Agustín Lara, Alejandro Algara and Tongolele.
