Babes in Toyland is an operetta composed by Victor Herbert with a libretto by Glen MacDonough (1870-1924), which wove together various characters from Mother Goose nursery rhymes into a Christmas-themed musical extravaganza. Following the extraordinary success of their stage musical The Wizard of Oz, which was produced in New York beginning in January 1903, producer Fred R. Hamlin and director Julian P. Mitchell hoped to create more family musicals. MacDonough had helped Mitchell with revisions to the Oz libretto by L. Frank Baum. Mitchell and MacDonough persuaded Victor Herbert to join the production.[citation needed] Babes in Toyland features some of Herbert's most famous songs - among them "Toyland", "March of the Toys", "Go To Sleep, Slumber Deep", and "I Can't Do the Sum". The theme song "Toyland", and the most famous instrumental piece from the operetta, "March of the Toys", occasionally show up on Christmas compilations.
