What is "polnareff's"

Polnareff's is an album by Michel Polnareff released in 1971 on AZ Disques. At the time of its release, Polnareff was "one of the most successful musicians in France", according to The Independent. The album reflected some very personal and serious issues for Polnareff, including the suicide of Europe 1 radio director Lucien Morisse, a close friend, to whom the song "Qui a tué grand'maman?" was dedicated. In 1997, the album was first reissued on compact disc by Universal Records, along with his albums Le Bal des Lazes and Love Me, Please Love Me.
