"D.I.S.C.O." is a Euro disco song by the French band Ottawan, written by Daniel Vangarde and Jean Kluger. It was originally recorded by Ottawan in French.
It was first recorded in 1979 and reached number 2 in the UK singles chart the following year.
The song's name comes from the lyrics in its chorus, in which a woman is claimed to be 'DISCO', with each letter of the word standing for a certain quality, except O which simply leads to singing 'oh, oh, oh' ("She is disco // She is D delirious // She is I incredible // She is S superficial // She is C complicated // She is O oh, oh, oh").
