Jean-Philippe Smet, known by his stage name Johnny Hallyday, French pronunciation: [dʒɔ.ni a.li.dɛ] (born 15 June 1943, Cité Malesherbes, Paris, France) is a French singer and actor. An icon in the French-speaking world since the beginning of his career, he has been called "the French Elvis". He was married for 15 years to popular Bulgarian-French singer Sylvie Vartan and the two were considered a "golden couple" for 20 years. Hallyday has completed 181 tours, had 18 platinum albums, and has sold more than 80 million records worldwide, making him one of the world's best-selling artists of all time. He announced his retirement from performing on 3 December 2007, saying that he would retire in 2009, after a farewell tour. However, Hallyday announced in March 2012 that he would perform in Los Angeles on 24 April, in Quebec City on 10 July and in New York City on 7 October, and he has continued to tour throughout the world (including Europe, North America, and Asia) through 2014.
Hallyday remains largely unknown outside of the Francophone world of France, Belgium, Switzerland, Canada, Guyana, Southeast Asia and Africa thus earning the nickname "the biggest rock star you've never heard of" in English-speaking countries.
Nevertheless, at an international level he is still considered as the only non-Anglophone rock musician having a large international reputation. He was made Chevalier (Knight) of the Légion d'honneur in 1997.
