Background: Jeanette Anna MacDonald (June 18, 1903 - January 14, 1965) was an American singer and actress best remembered for her musical films of the 1930s with Maurice Chevalier (The Love Parade, Love Me Tonight, The Merry Widow and One Hour With You) and Nelson Eddy (Naughty Marietta, Rose-Marie, and Maytime). During the 1930s and 1940s she starred in 29 feature films, four nominated for Best Picture Oscars (
Context: Unlike Nelson Eddy, who came from opera to film, MacDonald in the 1940s yearned to reinvent herself in opera. She began training for this goal with Lotte Lehmann, one of the leading opera stars of the early 20th century.  "When Jeanette MacDonald approached me for coaching lessons", wrote Lehmann, "I was really curious how a glamorous movie star, certainly spoiled by the adoration of a limitless world, would be able to devote herself to another, a higher level of art. I had the surprise of my life. There couldn't have been a more diligent, a more serious, a more pliable person than Jeanette. The lessons which I had started with a kind of suspicious curiosity, turned out to be sheer delight for me. She studied Marguerite with me--and lieder. These were the ones which astounded me most. I am quite sure that Jeanette would have developed into a serious and successful lieder singer if time would have allowed it."  MacDonald made her opera debut singing Juliette in Gounod's Romeo et Juliette in Montreal at His Majesty's Theatre (May 8 and 10, 1943). She quickly repeated the role in Quebec City (May 12), Ottawa, and Toronto. Her U.S. debut with the Chicago Opera Company (November 4, 11 and 15, 1944) was in the same role. She also sang Marguerite in Gounod's Faust with the Chicago Opera. In November 1945, she did two more performances of Romeo et Juliette and one of Faust in Chicago, and two Fausts for the Cincinnati Opera. On December 12, 1951, she did one performance of Faust with the Philadelphia Civic Grand Opera Company at the Academy of Music.  Claudia Cassidy, the music critic of the Chicago Tribune wrote: "Her Juliet is breathtakingly beautiful to the eye and dulcet to the ear." The same critic reviewed Faust: "From where I sit at the opera, Jeanette MacDonald has turned out to be one of the welcome surprises of the season... her Marguerite was better than her Juliet...beautifully sung with purity of line and tone, a good trill, and a Gallic inflection that understood Gounod's phrasing....You felt if Faust must sell his soul to the devil, at least this time he got his money's worth."
Question: Where did she perform in the US?
Answer: in Chicago, and two Fausts for the Cincinnati Opera.

Problem: Background: John Hoyer Updike (March 18, 1932 - January 27, 2009) was an American novelist, poet, short story writer, art critic, and literary critic. One of only three writers to win the Pulitzer Prize for Fiction more than once (the others were Booth Tarkington and William Faulkner), Updike published more than twenty novels, more than a dozen short-story collections, as well as poetry, art and literary criticism and children's books during his career.
Context: The principal themes in Updike's work are religion, sex, and America as well as death. Often he would combine them, frequently in his favored terrain of "the American small town, Protestant middle class", of which he once said, "I like middles. It is in middles that extremes clash, where ambiguity restlessly rules."  For example, the decline of religion in America is chronicled in In the Beauty of the Lilies (1996) alongside the history of cinema, and Rabbit Angstrom contemplates the merits of sex with the wife of his friend Reverend Jack Eccles while the latter is giving his sermon in Rabbit, Run (1960).  Critics have often noted that Updike imbued language itself with a kind of faith in its efficacy, and that his tendency to construct narratives spanning many years and books--the Rabbit series, the Henry Bech series, Eastwick, the Maples stories--demonstrates a similar faith in the transcendent power of fiction and language. Updike's novels often act as dialectical theological debates between the book itself and the reader, the novel endowed with theological beliefs meant to challenge the reader as the plot runs its course. Rabbit Angstrom himself acts as a Kierkegaardian Knight of Faith.  Describing his purpose in writing prose, Updike himself, in the introduction to his Early Stories: 1953-1975 (2004), wrote that his aim was always "to give the mundane its beautiful due." Elsewhere he famously said, "When I write, I aim my mind not towards New York but towards a vague spot east of Kansas." Some have suggested that the "best statement of Updike's aesthetic comes in his early memoir 'The Dogwood Tree'" (1962): "Blankness is not emptiness; we may skate upon an intense radiance we do not see because we see nothing else. And in fact there is a color, a quiet but tireless goodness that things at rest, like a brick wall or a small stone, seem to affirm."
