Task: Question Generation
Input (English): Passage: In 1970, Lennon and Ono went through primal therapy with Arthur Janov in Los Angeles, California. Designed to release emotional pain from early childhood, the therapy entailed two half-days a week with Janov for four months; he had wanted to treat the couple for longer, but they felt no need to continue and returned to London. Lennon's debut solo album, John Lennon/Plastic Ono Band (1970), was received with praise by many music critics, but its highly personal lyrics and stark sound limited its commercial performance. Critic Greil Marcus remarked, "John's singing in the last verse of 'God' may be the finest in all of rock." The album featured the song "Mother", in which Lennon confronted his feelings of childhood rejection, and the Dylanesque "Working Class Hero", a bitter attack against the bourgeois social system which, due to the lyric "you're still fucking peasants", fell foul of broadcasters. In January 1971, Tariq Ali expressed his revolutionary political views when he interviewed Lennon, who immediately responded by writing "Power to the People". In his lyrics to the song, Lennon reversed the non-confrontational approach he had espoused in "Revolution", although he later disowned the message, saying that it was borne out of guilt and a desire for approval from radicals such as Ali. Lennon became involved with Ali in a protest against the prosecution of Oz magazine for alleged obscenity. Lennon denounced the proceedings as "disgusting fascism", and he and Ono (as Elastic Oz Band) released the single "God Save Us/Do the Oz" and joined marches in support of the magazine.
Eager for a major commercial success, Lennon adopted a more accessible sound for his next album, Imagine (1971). Rolling Stone reported that "it contains a substantial portion of good music" but warned of the possibility that "his posturings will soon seem not merely dull but irrelevant". The album's title track later became an anthem for anti-war movements, while the song "How Do You Sleep?" was a musical attack on McCartney in response to lyrics on Ram that Lennon felt, and McCartney later confirmed, were directed at him and Ono. Lennon reflected on his jealous nature in the track "Jealous Guy", later immortalized by Roxy Music's chart-topping 1981 cover following Lennon's murder. In gratitude for his guitar contributions to Imagine, Lennon initially agreed to perform at Harrison's Concert for Bangladesh benefit shows in New York. Harrison refused to allow Ono to participate at the concerts, however, which resulted in the couple having a heated argument and Lennon pulling out of the event.
Output (English): What was the last name of the person that the song "How do you sleep" was a musical attack on?
