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: The Kinks' next single, "Waterloo Sunset", was released in May 1967. The lyrics describe two lovers passing over a bridge, with a melancholic observer reflecting on the couple, the Thames and Waterloo station. The song was rumoured to have been inspired by the romance between two British celebrities of the time, actors Terence Stamp and Julie Christie. Ray Davies denied this in his autobiography, and claimed in a 2008 interview, "It was a fantasy about my sister going off with her boyfriend to a new world and they were going to emigrate and go to another country." Despite its complex arrangement, the sessions for "Waterloo Sunset" lasted a mere ten hours; Dave Davies later commented on the recording: "We spent a lot of time trying to get a different guitar sound, to get a more unique feel for the record. In the end we used a tape-delay echo, but it sounded new because nobody had done it since the 1950s. I remember Steve Marriott of the Small Faces came up and asked me how we'd got that sound. We were almost trendy for a while." The single was one of the Kinks' biggest UK successes (hitting number two on Melody Maker's chart), and went on to become one of their most popular and best-known songs. Pop music journalist Robert Christgau called it "the most beautiful song in the English language", and AllMusic senior editor Stephen Thomas Erlewine cited it as "possibly the most beautiful song of the rock and roll era".
The songs on the 1967 album, Something Else By The Kinks, developed the musical progressions of Face to Face, adding English music hall influences to the band's sound. Dave Davies scored a major UK chart success with the album's "Death of a Clown". While it was co-written by Ray Davies and recorded by the Kinks, it was also released as a Dave Davies solo single. Overall, however, the album's commercial performance was disappointing, prompting the Kinks to rush out a new single, "Autumn Almanac", in early October. Backed with "Mister Pleasant", the single became another Top 5 success for the group. Andy Miller points out that, despite its success, the single marks a turning point in the band's career—it would be their last entry into the UK Top Ten for three years: "In retrospect, 'Autumn Almanac' marked the first hint of trouble for the Kinks. This glorious single, one of the greatest achievements of British 60s pop, was widely criticised at the time for being too similar to previous Davies efforts." Nick Jones of Melody Maker asked, "Is it time that Ray stopped writing about grey suburbanites going about their fairly unemotional daily business? ... Ray works to a formula, not a feeling, and it's becoming rather boring." Disc jockey Mike Ahern called the song "a load of old rubbish". Dave's second solo single, "Susannah's Still Alive", was released in the UK on 24 November. It sold a modest 59,000 copies, but failed to reach the Top 10. Miller states that "by the end of the year, the Kinks were rapidly sliding out of fashion".
What is the full name of the person whose sister the song Waterloo Sunset was about?
