The works are derived from the entertainment genre of pantomime that developed in England, presented either as they are in Britain or adapted for the American stage and tailored to American audiences.  Pantomime in America, as in England, is usually performed at Christmas time.  The entertainments, aimed at families, are based on nursery stories and fairy tales, and they incorporate songs (traditional, popular and new), slapstick comedy, often topical jokes, magic, some cross-dressing, local references, audience participation, and mild adult innuendo.

Modern pantomime includes songs, gags, slapstick comedy and dancing, employs gender-crossing actors, and combines topical humour with a story loosely based on a well-known fairy tale, fable or folk tale.  It is a participatory form of theatre, in which the audience is expected to sing along with certain parts of the music and shout out phrases to the performers.
