Burt Shevelove invited Sondheim to a party; Sondheim arrived before him, and knew no one else well. He saw a familiar face: Arthur Laurents, who had seen one of the auditions of "Saturday Night", and they began talking. Laurents told him he was working on a musical version of "Romeo and Juliet" with Leonard Bernstein, but they needed a lyricist; Betty Comden and Adolph Green, who were supposed to write the lyrics, were under contract in Hollywood. He said that although he was not a big fan of Sondheim's music, he enjoyed the lyrics from "Saturday Night" and he could audition for Bernstein. The following day, Sondheim met and played for Bernstein, who said he would let him know. The composer wanted to write music and lyrics; after consulting with Hammerstein, Bernstein told Sondheim he could write music later. In 1957, "West Side Story" opened; directed by Jerome Robbins, it ran for 732 performances. Sondheim has expressed dissatisfaction with his lyrics, saying that they do not always fit the characters and are sometimes too consciously poetic. Initially Bernstein was also credited as a co-writer of the lyrics; later, however, Bernstein offered Sondheim solo credit, as Sondheim had essentially done all of them. "The New York Times" review of the show never even mentioned the lyrics. Sondheim described the division of the royalties, saying that Bernstein received three percent and he received one percent. Bernstein suggested evening the percentage at two percent each, but Sondheim refused because he was satisfied just getting the credit. Sondheim later said he wished "someone stuffed a handkerchief in my mouth because it would have been nice to get that extra percentage".
