Some context: Edgar Yipsel "Yip" Harburg (born Isidore Hochberg, Yiddish: ysydvr hvkbrg; April 8, 1896 - March 5, 1981) was an American popular song lyricist who worked with many well-known composers. He wrote the lyrics to the standards "Brother, Can You Spare a Dime?"
Harburg and Gorney were offered a contract with Paramount: in Hollywood, Harburg worked with composers Harold Arlen, Vernon Duke, Jerome Kern, Jule Styne, and Burton Lane, and later wrote the lyrics for The Wizard of Oz, one of the earliest known "integrated musicals," for which he won the Academy Award for Best Music, Original Song for "Over the Rainbow."  Of his work on The Wizard of Oz, his son (and biographer) Ernie Harburg has said:  So anyhow, Yip also wrote all the dialogue in that time and the setup to the songs and he also wrote the part where they give out the heart, the brains and the nerve, because he was the final script editor. And he--there were eleven screenwriters on that--and he pulled the whole thing together, wrote his own lines and gave the thing a coherence and unity which made it a work of art. But he doesn't get credit for that. He gets lyrics by E. Y. Harburg, you see. But nevertheless, he put his influence on the thing.  Working in Hollywood did not stop Harburg's career on Broadway. In the 1940s, he wrote a series of "book" musicals with social messages, including the successful Bloomer Girl (1944), set during the Civil War, which was about temperance and women's rights activist Amelia Bloomer. Harburg's best known Broadway show, Finian's Rainbow (1947) was, in its original production, possibly the first Broadway musical with a racially integrated chorus line, and features his "When the Idle Poor Become the Idle Rich." It was made into a film in 1968 starring Fred Astaire and Petula Clark, directed by Francis Ford Coppola.

Some context: Gigi [ZiZi] is a 1958 American musical-romance film directed by Vincente Minnelli processed using MGM's Metrocolor. The screenplay by Alan Jay Lerner is based on the 1944 novella of the same name by Colette. The film features songs with lyrics by Lerner and music by Frederick Loewe, arranged and conducted by Andre Previn. In 1991, Gigi was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
Hollywood producer Arthur Freed first proposed a musicalization of the Colette novella to Alan Jay Lerner during the Philadelphia tryout of My Fair Lady in 1954. When Lerner arrived in Hollywood two years later, Freed was battling the Hays Code to bring his tale of a courtesan-in-training to the screen. Another roadblock to the project was the fact Colette's widower had sold the rights to her novella to Gilbert Miller, who planned to produce a film version of the 1954 stage adaptation by Anita Loos. It cost Freed more than $87,000 to purchase the rights from Miller and Loos.  Lerner's songwriting partner Frederick Loewe had expressed no interest in working in Hollywood, so Lerner agreed to write the screenplay only. He and Freed discussed casting; Lerner favored Audrey Hepburn, who had starred in the Broadway production written by Loos, but Freed preferred Leslie Caron, who had co-starred in An American in Paris for him. Both agreed Maurice Chevalier would be ideal for aging boulevardier Honore Lachaille, and Lerner proposed Dirk Bogarde for Gaston. Lerner agreed to write the lyrics if Freed could convince Bogarde and designer Cecil Beaton to join the project. He decided to approach Loewe once again, and when he suggested they compose the score in Paris, Loewe agreed.  In March 1957, the duo began working in Paris. When Chevalier, who already had agreed to appear in the film, first heard "Thank Heaven for Little Girls", he was delighted. When he discussed his waning interest in wine and women in favor of performing for an audience in cabarets, Chevalier inadvertently inspired the creation of another tune for his character, "I'm Glad I'm Not Young Anymore". The lyrics for another of his songs, the duet "I Remember It Well", performed with Hermione Gingold as his former love Madame Alvarez, were adapted from words Lerner had written for Love Life, a 1948 collaboration with Kurt Weill. "Say a Prayer for Me Tonight", a solo performed by Gigi, had been written for Eliza Doolittle in My Fair Lady but was removed during the pre-Broadway run. Lerner disliked the melody, but Loewe, Freed, and Minnelli voted to include it in the film.
