"Boom Bang-a-Bang" is a song recorded by Scottish singer Lulu. The song was written by Alan Moorhouse and Peter Warne. It was the British winning entry at the Eurovision Song Contest 1969, held in Madrid. It was the joint winner with three other entries: Salomé singing "Vivo cantando" for Spain, Lenny Kuhr singing "De troubadour" for the Netherlands, and Frida Boccara singing "Un jour, un enfant" for France. Over two decades after its first release, the song was included on a blacklist of banned songs issued by the BBC during the 1991 Gulf War.
