Problem: Background: Dion Francis DiMucci (born July 18, 1939), better known mononymously as Dion, is an American singer, songwriter whose work has incorporated elements of doo-wop, rock and R&B styles--and, most recently, straight blues. He was one of the most popular American rock and roll performers of the pre-British Invasion era. He had 39 Top 40 hits in the late 1950s and early 1960s as a solo performer, with the Belmonts or with the Del Satins. He is best remembered for the singles "Runaround Sue", "The Wanderer", "Ruby Baby" and "Lovers Who Wander", among his other hits.
Context: By the end of 1960, Dion had released his first solo album on Laurie, Alone with Dion, and the single "Lonely Teenager," which rose to No. 12 in the US charts. The name on his solo releases was simply "Dion." Follow-ups "Havin' Fun" and "Kissin' Game" had less success, and the signs were that Dion would drift onto the cabaret circuit. However, he then recorded, with a new vocal group, the Del-Satins, an up-tempo number co-written with Ernie Maresca. The record, "Runaround Sue," stormed up the U.S. charts, reaching No. 1 in October 1961, and No. 11 in the UK, where he also toured. "Runaround Sue" sold over a million copies, achieving gold disc status.  For the next single, Laurie promoted the A-side, "The Majestic," but it was the B-side, Maresca's "The Wanderer," which received more radio play and climbed swiftly up the charts to reach No. 2 in the U.S. in February 1962 and No. 10 in the UK (the 1976 re-release made the UK Top 20). "The Wanderer" has been used in the post-apocalyptic role-playing game Fallout 4, both in-game and in a trailer of the same name released in 2015.  By the end of 1961, Dion had become a major star, touring worldwide and making an appearance in the Columbia Pictures musical film Twist Around the Clock. He followed with a string of singles - "Lovers Who Wander" (No. 3), "Little Diane" (No. 8), "Love Came to Me" (No. 10) - in 1962, several of which he wrote or co-wrote. He also had successful albums with Runaround Sue and Lovers Who Wander.  At the end of 1962, Dion moved from Laurie to Columbia Records; he was the first rock and roll artist signed to the label, which was an anomaly considering that its then-A&R director, Mitch Miller, passionately loathed that particular genre of music. The first Columbia single, Leiber and Stoller's "Ruby Baby" (originally a hit for the Drifters) reached No. 2, while "Donna the Prima Donna" and "Drip Drop" (another remake of a Drifters hit) both reached No. 6 in late 1963. (Dion also recorded an Italian version of "Donna the Prima Donna" using the identical backup vocals.) His other Columbia releases were less successful, and problems with his addiction and changing public tastes, especially The British Invasion, saw a period of commercial decline.

Answer: 

Background: Tucker was born Sofya "Sonya" Kalish (in Russian, Sof'ia <<Sonia>> Kalish) in 1887 to a Jewish family en route to America from Tulchyn, Podolia Governorate, Russian Empire, now Vinnytsia Oblast, Ukraine. ("Sonya" is a nickname for the name "Sofya", the Russian form of the name Sophie.) The family adopted the surname Abuza, settled in Hartford, Connecticut, and opened a restaurant. At a young age, she began singing at her parents' restaurant for tips.
Context: In 1907, Tucker made her first theater appearance, singing at an amateur night in a vaudeville establishment. It was here that she was first made to wear blackface during performance, as her producers thought that the crowd would tease her for being "so big and ugly." By 1908, she had joined a burlesque show in Pittsburgh but was ashamed to tell her family that she was performing in a deep southern accent wearing burnt cork on her face. While touring later that year, luggage including her makeup kit was lost, and Tucker was allowed to go on stage without the blackface.  She then stunned the crowd by saying, "You all can see I'm a white girl. Well, I'll tell you something more: I'm not Southern. I'm a Jewish girl and I just learned this Southern accent doing a blackface act for two years. And now, Mr. Leader, please play my song." Tucker also began integrating "fat girl" humor, which became a common thread in her acts. Her songs included "I Don't Want to Get Thin" and "Nobody Loves a Fat Girl, But Oh How a Fat Girl Can Love."  In 1909, at the age of 22, Tucker performed with the Ziegfeld Follies. Though she was a hit, the other female stars refused to share the spotlight with her, and the company was forced to let her go. This caught the attention of William Morris, a theater owner and future founder of the William Morris Agency, which would become one of the largest and most powerful talent agencies of the era. Two years later, Tucker released "Some of These Days" on Edison Records, written by Shelton Brooks. The title of the song was later used as the title of Tucker's 1945 biography.  In 1921, Tucker hired pianist and songwriter Ted Shapiro as her accompanist and musical director, a position he would keep throughout her career. Besides writing a number of songs for her, Shapiro became part of her stage act, playing piano on stage while she sang, and exchanging banter and wisecracks with her in between numbers. Tucker remained a popular singer through the 1920s and became friends with stars such as Mamie Smith and Ethel Waters, who introduced her to jazz. Tucker learned from these talented women and became one of the first performers to introduce jazz to white vaudeville audiences.  In 1925, Jack Yellen wrote one of her most famous songs, "My Yiddishe Momme". The song was performed in large American cities where there were sizable Jewish audiences. Tucker explained, "Even though I loved the song and it was a sensational hit every time I sang it, I was always careful to use it only when I knew the majority of the house would understand Yiddish. However, you didn't have to be a Jew to be moved by My Yiddishe Momme." During the Hitler regime, the song was banned by the German government for evoking Jewish culture.
