Question: Who wrote a pop standard that was originally an instrumental track (or recurring theme) written for the 1960 Broadway version of the 1958 British play "A Taste of Honey" that was also made into the film daptation of the play of the same name by Shelagh Delaney?
Sentence (from "A Taste of Honey (film)"): It is an exemplar of a gritty genre of British film that has come to be called kitchen sink realism and was the inspiration behind the song "Your Mother Should Know", which is on the 1967 album "Magical Mystery Tour" by The Beatles.
Relevant evidence: No
