A dance party (also referred to as "a dance") is a social gathering where dancing is the primary activity. Some dance parties are held in a casual setting and open to the public, such as a rave, or those held in nightclubs and discothèques. Other types of dance parties may be a formal or semi-formal private event which often require guests to don formal wear and have an invitation or membership within the community hosting the event, such as school dances and Cotillions. Guests of formal dances often attend in pairs, as consorts, or "dates", for one another. The term "stag" refers to going without a consort, to a dance organized for couples. Dances commonly take place during the evening, although some are held earlier during the daytime; such events are known as tea dances.

Casual dances are dances that do not have a formal dress requirement; these may include school and community events, raves, evening entertainments provided for guests aboard a cruise ship, and events organized for certain holidays, such as Halloween and Mardis Gras.

Peter "Pete" Tong (born July 30, 1960) is an English DJ who works for BBC Radio 1. He is the host of programmes such as Essential Mix and Essential Selection on the radio service, which can be heard through Internet radio streams, for his record label FFRR Records, and for his own performances at nightclubs and music festivals. Tong has worked as a record producer and is known by the nickname of Lord of the Dance.

The phrase "It's all gone Pete Tong", where the name is used as rhyming slang for "wrong", was reputedly first coined by Paul Oakenfold in late 1987 in an article about acid house called "Bermondsey Goes Balearic" for Terry Farley and Pete Heller's Boys Own fanzine. It's All Gone Pete Tong is also the title of a 2004 film which portrays a fictional DJ's experiences as he realizes he is becoming deaf. Tong appears briefly in the film. It is also the name Tong has adopted for his club night at the nightclub Pacha in Ibiza.

In 2008 he was involved with the founding of the International Music Summit in Ibiza.
