I’m sorry, I don’t know if William Wyler ever composed or wrote poetry.
#1 is William Walton. Orchestras have been doing concert for the last few years where someone like Christopher Plummer reads the Chorus and the Henry speeches while the orchestra plays a suite of pieces from the soundtrack.
#2 is Ralph Vaughn Williams, composer of many symphonic and vocal works that involve the poetry of
#3, Walt Whitman, American poet and luminary.
DQ1: Are you American?
DQ2: Are you celebrated for your achievements in The Arts, broadly defined?
IQ1: Were you the sole companion of a very lonely man?
IQ2: Did you join the Allman Brothers Band on guitar in the late 1980s?
IQ3: Did you start a band when you were 16 and then play in that band for the next 30+ years?
Correct on Harrison (and thanks to the Simpsons for inspiring the question).
IQ2 was looking for Wilbur Turnblad, the father of Tracy Turnblad, in the show “Hairspray.”
IQ3 was looking for Hiram Walker, who developed Canadian Club whisky. Check their old ads; you’ll see that it was marketed as “the best in the house, in 87 lands.”
IQ1: Did the debut of your opera in Paris cause a riot?
IQ2: Are you a character from that opera, who was also a well known German Minnesinger? (And the author of the main source for another opera by that same composer.)
IQ3: Are you the composer of the opera ‘Die Freischütz’?
#1 is a reference to the Paris performance of Richard Wagner’s ‘Tannhäuser’. Against the best advice of the directors of the Paris Opera, Wagner insisted on having the ballet in the first act. The corps de ballet were all mistresses of the Paris jockey club, who were accustomed to having a long, drunken dinner, showing up at the opera in time for the third act, and then going off with their girlfriends. When they discovered that the ballet was long past, they caused a significant scene.
#2 is Wolfram von Eschenbach, a German Minnesinger of the 12th century who is a character in ‘Tannhäuser’. He was also the author of ‘Tristan’, which Wagner used as the basis for his opera ‘Tristan und Isolde’. It is Wolfram who sings the beautiful apostrophe to the evening star ‘O du, mein holder Abendstern’ in the last act of ‘Tannhäuser’.
#3 is Carl Maria von Weber, a German composer of the early 19th century. ‘Der Frieschütz’ is easily his most famous work.
I’ll claim two DQs for all that, if you’ll allow - you did say Wagner, after all.
