Given the task definition and input, reply with output. 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: After the murder of Lennon in December 1980, Harrison rewrote the lyrics to his song "All Those Years Ago" in Lennon's honour. With Starr on drums and McCartney and his wife, Linda, contributing backing vocals, the song was released as a single in May 1981. McCartney's own tribute, "Here Today", appeared on his Tug of War album in April 1982. In 1987, Harrison's Cloud Nine album included "When We Was Fab", a song about the Beatlemania era.When the Beatles' studio albums were released on CD by EMI and Apple Corps in 1987, their catalogue was standardised throughout the world, establishing a canon of the twelve original studio LPs as issued in the UK plus the US LP version of Magical Mystery Tour. All the remaining material from the singles and EPs that had not appeared on these thirteen studio albums was gathered on the two-volume compilation Past Masters (1988). Except for the Red and Blue albums, EMI deleted all its other Beatles compilations – including the Hollywood Bowl record – from its catalogue.In 1988, the Beatles were inducted into the Rock and Roll Hall of Fame, their first year of eligibility. Harrison and Starr attended the ceremony with Lennon's widow, Yoko Ono, and his two sons, Julian and Sean. McCartney declined to attend, citing unresolved "business differences" that would make him "feel like a complete hypocrite waving and smiling with them at a fake reunion". The following year, EMI/Capitol settled a decade-long lawsuit filed by the band over royalties, clearing the way to commercially package previously unreleased material.
