In 1974 Claude-Michel Schonberg wrote the music and the lyrics of the song "Le Premier Pas", which became the number 1 hit in France that year and sold over 1 million copies. Le Premier Pas was produced by Franck Pourcel.
Claude-Michel Schonberg's latest project with Boublil is The Pirate Queen, a musical about the 16th century Irish pirate, chieftain and adventuress Grace O'Malley. The Pirate Queen completed its 8-week pre-Broadway tryout at Chicago's Cadillac Palace Theatre on November 26, 2006.
The show underwent further development in preparation for its Broadway previews at the Hilton Theater in March 2007. The Broadway opening date was April 5, 2007. Miss Saigon co-lyricist Richard Maltby, Jr. came on-board to work with Boublil on revisions to the book and lyrics. Additionally, Graciela Daniele worked on the musical staging.
