X is a show tune from the 1945 Rodgers and Hammerstein musical Carousel.
In the musical, in the second act, Nettie Fowler, the cousin of the female protagonist Julie Jordan, sings X to comfort and encourage Julie when her husband, Billy Bigelow, the male lead, kills himself to avoid capture during a failed robbery. It is reprised in the final scene to encourage a graduation class of which Louise (Billy and Julie's daughter) is a member. Billy watches this ceremony during his return to earth.
The song is also sung at association football clubs around the world, where it is performed by a massed chorus of supporters on matchday; this tradition began at Y in the early 1960s and later spread to several other clubs
