Q: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Passage: Sean was Lennon's only child with Ono. Sean was born on 9 October 1975 (Lennon's thirty-fifth birthday), and John took on the role of househusband. Lennon began what would be a five-year hiatus from the music industry, during which time he gave all his attention to his family. Within the month, he fulfilled his contractual obligation to EMI/Capitol for one more album by releasing Shaved Fish, a compilation album of previously recorded tracks. He devoted himself to Sean, rising at 6 am daily to plan and prepare his meals and to spend time with him. He wrote "Cookin' (In the Kitchen of Love)" for Starr's Ringo's Rotogravure (1976), performing on the track in June in what would be his last recording session until 1980. He formally announced his break from music in Tokyo in 1977, saying, "we have basically decided, without any great decision, to be with our baby as much as we can until we feel we can take time off to indulge ourselves in creating things outside of the family." During his career break he created several series of drawings, and drafted a book containing a mix of autobiographical material and what he termed "mad stuff", all of which would be published posthumously.
Lennon emerged from his five-year interruption in music recording in October 1980, when he released the single "(Just Like) Starting Over". The following month saw the release of Double Fantasy, which contained songs written during a June 1980 journey to Bermuda on a 43-foot sailing boat. The music reflected Lennon's fulfilment in his new-found stable family life. Sufficient additional material was recorded for a planned follow-up album Milk and Honey, which was released posthumously, in 1984. Double Fantasy was jointly released by Lennon and Ono very shortly before his death;  the album was not well received and drew comments such as Melody Maker's "indulgent sterility ... a godawful yawn".
A:
What is the last name of the person who fulfilled his contractual obligation to EMI/Capitol for one one more album by releasing Shaved Fish?
