:This article is about the comic opera by Arthur Sullivan. For other uses, see The Zoo (disambiguation). The Zoo is a one-act comic opera, with music by Arthur Sullivan and a libretto by B. C. Stephenson, writing under the pen name of Bolton Rowe. It premiered on June 5 1875 at the St. James's Theatre in London (as an afterpiece to W. S. Gilbert's Tom Cobb), concluding its run five weeks later, on June 28 1875, at the Haymarket Theatre. There were brief revivals in late 1875, and again in 1879, before the opera was shelved.

The score was not published in Sullivan's lifetime, and it lay dormant until Terence Rees purchased the composer's autograph at auction in 1966 and arranged for publication. The opera is in one act without spoken dialogue, running about 40 minutes. Like Trial by Jury and Cox and Box, it has been staged as a curtain-raiser to the shorter Gilbert and Sullivan operas. Triple-bills of Sullivan's three one-act operas have also proved successful.

Zoo were a dance troupe who appeared on the weekly British music series Top of the Pops between 1981 and 1983.

Like previous dance troupes Pan's People, Ruby Flipper and their immediate predecessors Legs & Co., Zoo were put together and choreographed by Flick Colby (whose credit on the TOTP end credit changed from "Choreographer" to "Dance Director" on Zoo's debut). However, unlike the previous troupes, Zoo were formed as a reparatory dance group with an ever-changing line-up, featuring a mixture of male and female multi-racial dancers with backgrounds in classical dance, the circus and the disco dancing scene.

Zoo were credited as appearing 45 times on TOTP between 5 November 1981 and 27 September 1983, although members of the troupe still appeared on the show in this time and beyond their residence outside their capacity as members of Zoo.

Their first appearance on TOTP featured a routine to the Electric Light Orchestra's "Twilight".
