Your Own Thing is a rock-styled musical comedy loosely based on Twelfth Night by William Shakespeare. It premiered off-Broadway in early 1968. The music and lyrics are by Hal Hester and Danny Apolinar with the book adaptation by Donald Driver, who also directed the original production. The show was a success, running for 933 performances and then touring and playing in London and Australia.
The show is set in the present (late 1960s) in the land of Illyria, which looks very much like New York City. It is a tale of separated twins, mistaken identities, love triangles and "doing your own thing".
It opens when a raging storm wrecks the ship on which a rock duet is traveling. They are "identical" twenty year old twins, Viola and Sebastian. Even in this life-threatening situation, they are bickering as usual (No One's Perfect Dear). In the confusion of the ship sinking, the twins are parted. Viola lands in Illyria where, being told Sebastian drowned, she expresses her loneliness in the strange city (The Flowers). A mysterious stranger gives her a business-card with a job offer. The all-male rock quartet "The Apocalypse” is short one member since Disease was drafted to fight in Vietnam.
