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 Sitwells looked after their protégé both materially and culturally, giving him not only a home but a stimulating cultural education. He took music lessons with Ernest Ansermet, Ferruccio Busoni and Edward J. Dent. He attended the Russian ballet, met Stravinsky and Gershwin, heard the Savoy Orpheans at the Savoy Hotel and wrote an experimental string quartet heavily influenced by the Second Viennese School that was performed at a festival of new music at Salzburg in 1923. Alban Berg heard the performance and was impressed enough to take Walton to meet Arnold Schoenberg, Berg's teacher and the founder of the Second Viennese School.In 1923, in collaboration with Edith Sitwell, Walton had his first great success, though at first it was a succès de scandale. Façade was first performed in public at the Aeolian Hall, London, on 12 June. The work consisted of Edith's verses, which she recited through a megaphone from behind a screen, while Walton conducted an ensemble of six players in his accompanying music. The press was generally condemnatory. Walton's biographer Michael Kennedy cites as typical a contemporary headline: "Drivel That They Paid to Hear". The Daily Express loathed the work, but admitted that it was naggingly memorable. The Manchester Guardian wrote of "relentless cacophony". The Observer condemned the verses and dismissed Walton's music as "harmless". In The Illustrated London News, Dent was much more appreciative: "The audience was at first inclined to treat the whole thing as an absurd joke, but there is always a surprisingly serious element in Miss Sitwell's poetry and Mr Walton's music ... which soon induced the audience to listen with breathless attention." In The Sunday Times, Ernest Newman said of Walton, "as a musical joker he is a jewel of the first water".Among the audience were Evelyn Waugh, Virginia Woolf and Noël Coward. The last was so outraged by the avant-garde nature of Sitwell's verses and the staging, that he marched out ostentatiously during the performance. The players did not like the music: the clarinettist, Charles Draper asked the composer, "Mr Walton, has a clarinet player ever done you an injury?" Nevertheless, the work soon became accepted, and within a decade Walton's music was used for the popular Façade ballet, choreographed by Frederick Ashton.
What is the last name of the person who asked the composer that  met Stravinsky and Gershwin whether "...a clarinet player ever done you an injury?"?
