Question: Which ballet piece,  now one of the most popular of all ballets despite its initial failure, inspired "Somewhere" the song from the 1957 Broadway musical "West Side Story?"
Sentence (from "West Side Story (soundtrack)"): Released in 1961, the soundtrack spent 54 weeks at No. 1 on Billboard's album charts, giving it the longest run at No. 1 of any album in history, although some lists instead credit Michael Jackson's "Thriller", on the grounds that "West Side Story" was listed on a chart for stereo albums only at a time when many albums were recorded in mono.
Relevant evidence: No
