Jean-Philippe Léo Smet (15 June 1943 – 5 December 2017), better known by his stage name Johnny Hallyday, was a French rock and roll and pop singer and actor, credited with having brought rock and roll to France.

During a career spanning 57 years, Hallyday released 79 albums and sold more than 110 million records worldwide, mainly in the French-speaking world, making him one of the best-selling artists in the world. He had five diamond albums, 40 gold albums, 22 platinum albums and earned ten Victoires de la Musique. He sang an estimated 1,154 songs and performed 540 duets with 187 artists. Credited for his strong voice and his spectacular shows, he sometimes arrived by entering a stadium through the crowd and once by jumping from a helicopter above the Stade de France, where he performed nine times. Among his 3,257 shows completed in 187 tours, the most memorable were at Parc des Princes in 1993, at the Stade de France in 1998, just after France's win in the 1998 FIFA World Cup, as well as at the Eiffel Tower in 2000, which had record-breaking ticket sales for a French artist. A million spectators gathered to see his performance at the Eiffel Tower, with some 10 million watching on television.
