Question: A song with lyrics by Charles Hart featured in a 1986 musical was written by a man who has composed how many musicals total?
Context: Lynn Ahrens (born October 1, 1948) is an American writer and lyricist for the musical theatre, television and film.  She has collaborated with Stephen Flaherty for many years.  She won the Tony Award, Drama Desk Award, and Outer Critics Circle Award for the Broadway musical "Ragtime".  Together with Flaherty, they have written many musicals, including "Lucky Stiff", "Once on This Island", "My Favorite Year", "Ragtime", "Seussical", "A Man of No Importance", "Dessa Rose", "The Glorious Ones", and most recently seen on Broadway, "Rocky the Musical". "Somewhere In France Is the Lily" is a World War I march composed in 1918 by Joseph E. Howard with lyrics written by Philander Chase Johnson.  It became a hit twice in 1918, charting when released by Charles Hart and by Henry Burr.  The song presents a young couple separated by war but held together by love and the sentimental value of lily flowers. Bend It Like Beckham the Musical is a musical with music by Howard Goodall, lyrics by Charles Hart, and a book by Gurinder Chadha and Paul Mayeda Berges.  Based on the 2002 film of the same name, the musical made its West End and world premiere at the Phoenix Theatre in May 2015. "Anything But Lonely" is a 1989 single by Sarah Brightman.  The song is from the musical "Aspects of Love".  The music was written by Andrew Lloyd Webber and the lyrics by Don Black and Charles Hart.  The single peaked at #79 in the UK charts. Andrew Lloyd Webber, Baron Lloyd-Webber (born 22 March 1948) is an English composer and impresario of musical theatre.  Several of his musicals have run for more than a decade both in the West End and on Broadway.  He has composed 13 musicals, a song cycle, a set of variations, two film scores, and a Latin Requiem Mass.  Several of his songs have been widely recorded and were hits outside of their parent musicals, notably "The Music of the Night" from "The Phantom of the Opera", "I Don't Know How to Love Him" from "Jesus Christ Superstar", "Don't Cry for Me, Argentina" and "You Must Love Me" from "Evita", "Any Dream Will Do" from "Joseph and the Amazing Technicolor Dreamcoat" and "Memory" from "Cats".  In 2001 the "New York Times" referred to him as "the most commercially successful composer in history".  Ranked the "fifth most powerful person in British culture" by "The Telegraph" in 2008, the lyricist Don Black stated "Andrew more or less single-handedly reinvented the musical." Love Changes Everything is a song from the musical "Aspects of Love", composed by Andrew Lloyd Webber, with a lyric written by Charles Hart and Don Black.  It is first sung in the musical by the character Alex Dillingham, which was originated by Michael Ball in both the London and Broadway casts.  The song was released as a single in 1989, also sung by Ball, and stayed in the UK singles chart for 14 weeks, peaking at #2 and becoming Ball's signature tune.  The song was later featured on Ball's 1992 self-titled debut album and "Love Changes Everything: The Collection". "The Music of the Night" (also labeled as just "Music of the Night") is a song from the 1986 musical "The Phantom of the Opera".  The music was written by Andrew Lloyd Webber with lyrics by Charles Hart.  It has appeared on multiple soundtracks of the musical, such as the original cast version in which English actor Michael Crawford sings the song. "All I Ask of You" is a song performed by Cliff Richard and Sarah Brightman during the 1986 English musical "The Phantom of the Opera".  It was written by Andrew Lloyd Webber, Charles Hart and Richard Stilgoe, and produced by Lloyd Webber.  The duet was meant for characters Christine Daaé and Raoul during the stage musical.  An operatic pop piece, its lyrics serve as dialogue between the two characters and discuss themes such as commitment and romance.  During the stage performance of "All I Ask of You", Steve Barton performs as the role of Raoul instead of Richard.  Like Lloyd Webber's song "The Music of the Night", "All I Ask of You" was compared to the music found in Giacomo Puccini's 1910 opera "La fanciulla del West". Charles Hart (born 3 June 1961) is a British lyricist, songwriter and musician.  He is best known for writing the lyrics to, and contributing to the book of Andrew Lloyd Webber's stage musical "The Phantom of the Opera" and for writing the lyrics to Bend It Like Beckham the Musical.  He also co-wrote (with Don Black) the lyrics to Lloyd Webber's 1989 musical "Aspects of Love".  Hart also re-wrote Glenn Slater's lyrics for "Love Never Dies", the sequel to "Phantom". The Phantom of the Opera is a musical with music by Andrew Lloyd Webber and lyrics by Charles Hart and Richard Stilgoe.  Lloyd Webber and Stilgoe also wrote the musical's book together.  Based on the French novel "Le Fantôme de l'Opéra" by Gaston Leroux, its central plot revolves around a beautiful soprano, Christine Daaé, who becomes the obsession of a mysterious, disfigured musical genius living in the subterranean labyrinth beneath the Opera Garnier.
