"5.15" (sometimes written "5:15" or "5'15") is a song written by Pete Townshend of British rock band The Who from their second rock opera, Quadrophenia (1973). The song reached #20 on the UK Singles Chart, while the 1979 re-release (accompanying the film and soundtrack album) reached #45 on the Billboard Hot 100.

Although written as "5.15" on the single cover, on the back cover of Quadrophenia (the album from which the song is taken) it is written as "5:15".

In the song, the main character Jimmy has taken the titular train to Brighton, consumed a lot of drugs, recollecting his life with the Mods, the cultural movement to which he belongs (even if he has dropped out for now), and their duels with the Rockers. Jimmy's memories are extremely disjointed, consisting mainly of anger, confusion, violence, sexual frustration, and rootlessness.

"5.15", like many of the songs from Quadrophenia, is self-referential - "M-m-m-my generation" is a line - and thus represents an angrily self-centered, teenage disconnection with society, family and the opposite sex. 'Jimmy' was "born in the war" (that is, World War II and its aftermath) and does not understand why he should care about it (or anything) in the context of his extravagant Mod values.

David Bowie ( /ˈboʊ.i/ BOH-ee; born David Robert Jones on 8 January 1947) is an English musician, actor, record producer and arranger. A major figure for over four decades in the world of popular music, Bowie is widely regarded as an innovator, particularly for his work in the 1970s. He is known for his distinctive voice and the intellectual depth and eclecticism of his work.

Bowie first caught the eye and ear of the public in July 1969, when his song "Space Oddity" reached the top five of the UK Singles Chart. After a three-year period of experimentation he re-emerged in 1972 during the glam rock era with the flamboyant, androgynous alter ego Ziggy Stardust, spearheaded by the hit single "Starman" and the album The Rise and Fall of Ziggy Stardust and the Spiders from Mars. Bowie's impact at that time, as described by biographer David Buckley, "challenged the core belief of the rock music of its day" and "created perhaps the biggest cult in popular culture." The relatively short-lived Ziggy persona proved merely one facet of a career marked by continual reinvention, musical innovation and striking visual presentation.

Donald John Trump, Sr. (born June 14, 1946) is an American business magnate, television personality and author. He is the chairman and president of The Trump Organization and the founder of Trump Entertainment Resorts. Trump's extravagant lifestyle, outspoken manner and role on the NBC reality show The Apprentice have made him a well-known celebrity who was No. 17 on the 2011 Forbes Celebrity 100 list. He is well-known as a real-estate developer who amassed vast hotel, casino, and other real-estate properties, in the New York City area and around the world.

Trump is the son of Fred Trump, a wealthy New York City real-estate developer. He worked for his father's firm, Elizabeth Trump & Son, while attending the Wharton School of the University of Pennsylvania, and in 1968 officially joined the company. He was given control of the company in 1971 and renamed it The Trump Organization.

In 2010, Trump expressed an interest in becoming a candidate for President of the United States in the 2012 election. In May 2011, he announced he would not be a candidate, but a few weeks later he said he had not completely ruled out the possibility. In December 2011, Trump was suggested as a possible Vice Presidential selection by Michele Bachmann. Bachmann has since suspended her presidential campaign.
