Oh, Boy! is a musical in two acts, with music by Jerome Kern and book and lyrics by Guy Bolton and P. G. Wodehouse. The story concerns befuddled George, who elopes with Lou Ellen, the daughter of Judge Carter. He must win over her parents and his Quaker aunt. His dapper polo champion friend Jim is in love with madcap actress Jackie, but George must hide her while she extricates herself from a scrape with a bumbling constable whom she punched at a party raid.
