Released on this day in 1981, "Under Pressure" is a song by Queen, written and recorded in collaboration with David Bowie. It was included on Queen's 1982 album Hot Space. The song reached number one on the UK Singles Chart, becoming the band's second number-one hit in their home country (after 1975's "Bohemian Rhapsody"). The song was played live at every Queen concert from 1981 until the end of Queen's touring career in 1986.
