Johnny Hallyday was France's first and only full-fledged rock star. Other French artists may have been influenced by rock & roll, but none was as beholden to the original sources, or as enduringly successful, as Hallyday. He was a distinctly French phenomenon, never achieving recognition in the U.S. or U.K.; certainly, part of the reason was that a good chunk of his repertoire consisted of French-language covers of early American rock hits.
