input: The stage was now set for the height of the band's popularity. On November 21, 1980, REO Speedwagon released Hi Infidelity, which represented a change in sound, going from hard rock to more pop-oriented material. Hi Infidelity spawned four hit singles written by Richrath and Cronin, including the chart-topping "Keep On Loving You" (Cronin), plus "Take It on the Run" (#5) (Richrath), "In Your Letter" (#20) (Richrath), and "Don't Let Him Go" (#24) (Cronin), and remained on the charts for 65 weeks, 32 of which were spent in the top ten, including 15 weeks atop the Billboard 200. Hi Infidelity sold over 10 million copies and set the bar for rock bands across the country. The band's follow-up album, Good Trouble, was released in 1982. Although it was not as successful as its predecessor, the album performed moderately well commercially, featuring the hit singles "Keep the Fire Burnin'" (U.S. #7), "Sweet Time" (U.S. #26) and the Album Rock chart hit "The Key." The band came storming back two years later with Wheels Are Turnin', an album that included the #1 hit single "Can't Fight This Feeling" plus three more hits: "I Do' Wanna Know" (U.S. #29), "One Lonely Night" (U.S. #19), and "Live Every Moment" (U.S. #34). REO Speedwagon toured the US in 1985, including a sold-out concert in Madison, Wisconsin in May. On July 13, on the way to a show in Milwaukee, the band made a stop in Philadelphia to play at the US leg of Live Aid, which broke a record for number of viewers. They performed "Can't Fight This Feeling" and "Roll With the Changes," which featured members of the Beach Boys, the band members' families, and Paul Shaffer on stage for backing vocals. 1987's Life as We Know It saw a decline in sales, but still managed to provide the band with the top-20 hits "That Ain't Love" (U.S. #16) and "In My Dreams" (U.S. #19). The Hits (1988) is a compilation album from REO Speedwagon. It contains new tracks "Here With Me" and "I Don't Want to Lose You." "Here with Me" cracked the top 20 on the Billboard Hot 100 and the top ten on the Adult Contemporary chart. They were the last songs recorded with Gary Richrath and Alan Gratzer

input: On October 13, 1961, she received a call from an agent who told her a producer was interested in working with her. When she was told it was Alfred Hitchcock who, while he was watching The Today Show, saw her in a commercial for a diet drink called Sego, she agreed to sign a seven-year contract. During their first meeting, the two talked about everything except the role he was considering her for. Hedren was convinced for several weeks it was for his television series, Alfred Hitchcock Presents. Hitchcock later said, "I was not primarily concerned with how she looked in person. Most important was her appearance on the screen, and I liked that immediately. She has a touch of that high-style, lady-like quality which was once well-represented in films by actresses like Irene Dunne, Grace Kelly, Claudette Colbert, and others but which is now quite rare." Hitchcock put Hedren through an extensive color screen test that lasted two days and cost $25,000, doing scenes from his previous films, such as Rebecca, Notorious and To Catch a Thief with actor Martin Balsam. According to Balsam, Hedren was very nervous but studied every line, did every move she was asked to, and tried to do everything right. Hitchcock asked costume designer Edith Head to design clothes for Hedren's private life and he personally advised her about wine and food. He also insisted for publicity purposes that her name should be printed only in single quotes, 'Tippi'. The press mostly ignored this directive from the director, who felt that the single quotes added distinction and mystery to her name. Hitchcock was impressed with Hedren. As production designer Robert F. Boyle explained, "Hitch always liked women who behaved like well-bred ladies. Tippi generated that quality." Afterward, Hedren was invited to lunch with Hitchcock, his wife, Alma, and Lew Wasserman, head of Universal, at one of Hitchcock's favorite restaurants, Chasen's. There she was presented with a golden pin of three birds in flight, adorned by three tiny seed pearls, and was asked by Hitchcock to play the leading role in his upcoming film The Birds. "I was so stunned. It never occurred to me that I would be given a leading role in a major motion picture. I had great big tears in my eyes", Hedren later recalled.

input: Voldemort does not appear in Harry Potter and the Half-Blood Prince, although his presence and actions are felt: he once again declares war, and begins to rise to power once more. He murders Amelia Bones of the Department of Magical Law Enforcement, and begins to target members of the Order of the Phoenix, including Emmeline Vance. Rowling uses several chapters as exposition to establish Voldemort's backstory. In a series of flashbacks, using the pensieve as a plot device, she reveals that Voldemort was the son of the witch Merope Gaunt and a Muggle called Tom Riddle. Riddle abandoned Merope before their child's birth, soon after which Merope died, just hours after giving birth. After living in an orphanage, young Riddle met Dumbledore, who told him he was a wizard and arranged for him to attend Hogwarts. Riddle was outwardly a model student, but was in reality a psychopath who takes sadistic pleasure in using his powers to harm and control people. He eventually murdered his father and grandparents as revenge for abandoning him. The book also discusses Riddle's hatred of "Muggles", his obsession with Horcruxes, and his desire to split his soul to achieve immortality. Rowling stated Voldemort's conception under the influence of a love potion symbolises the prejudicial circumstances under which he was brought into the world. In the main plot of the book, Voldemort's next step is to engineer an assault on Hogwarts, and to attack Dumbledore. This is accomplished by Draco Malfoy, who arranges transportation of Death Eaters into Hogwarts by a pair of Vanishing Cabinets, which bypass the extensive protective enchantments placed around the school. The cabinets allow Voldemort's Death Eaters to enter Hogwarts, where battle commences and Dumbledore is cornered. Hogwarts professor (and re-doubled agent) Severus Snape uses the Killing Curse against Dumbledore when Draco could not force himself to do so.
