Some context: Graziano was the son of Ida Scinto and Nicola Barbella. Barbella, nicknamed Fighting Nick Bob, was a boxer with a brief fighting record. Born in Brooklyn, Graziano later moved to an Italian enclave centered on East 10th Street, between First Avenue and Avenue A in Manhattan's East Village. He grew up as a street fighter and learned to look after himself before he could read or write.
Graziano heard from a couple of his friends about a tournament going on with a gold medal for the winner. He entered under the name of Joe Giuliani and was trained by Tobias (Toby) Zaccaria of Kings County (Brooklyn), NY. He fought four matches and ended up winning the New York Metropolitan Amateur Athletic Union Boxing Competition (1939). He sold the gold medal for $15 and decided that boxing was a good way to make cash. A couple of weeks into amateur fighting, Graziano was picked up for stealing from a school. He went to Coxsackie Correctional Facility, where he spent three weeks, with boyhood friend Jake LaMotta, and then he went on to the New York City Reformatory where he spent five months. After he got out of the reformatory, he headed back to the gym to earn money and while there, met Eddie Cocco who started his professional career. He entered the ring under the name Robert Barber. A couple of weeks later, Graziano was charged with a probation violation and sent back to reform school where he was charged with starting a minor riot. He was then sent to Rikers Island. When Graziano got out of jail he enlisted in the military but went AWOL after punching a captain. He escaped from Fort Dix in New Jersey and started his real boxing career under the name of "Rocky Graziano". He won his first couple of bouts. After gaining popularity under the name of Graziano, he was found by the military. After his fourth bout, he was called into manager's office to speak with a couple of military personnel. Expecting to be prosecuted and sent back to the military or jail, he fled. He returned to the military a week later. He turned himself in, but he was pardoned and given the opportunity to fight under the army's aegis.

Some context: Christina Maria Aguilera (born December 18, 1980) is an American singer, songwriter, actress, reality show personality and television personality. Born in Staten Island, New York and raised in Rochester and Wexford, Pennsylvania, she appeared on the television series Star Search and The Mickey Mouse Club in her early years. After recording "Reflection", the theme for Disney's 1998 film Mulan, Aguilera signed with RCA Records. She rose to prominence with her 1999 self-titled debut album that spawned the US Billboard Hot 100 number-one singles "Genie in a Bottle", "What a Girl Wants", and "Come On Over Baby
Christina Maria Aguilera was born in the Staten Island borough of New York City, New York, on December 18, 1980, to Shelly Loraine Kearns (nee Fidler), a musician, and Fausto Xavier Aguilera, a United States Army soldier. Her father is Ecuadorian, while her mother has German, Irish, Welsh, and Dutch ancestry. Her family moved frequently because of her father's military service, and lived in places including New Jersey, Texas, New York, and Japan. Aguilera and her mother alleged that her father was physically and emotionally abusive, claims which he denied; Aguilera used music as a form of escape from her turbulent household. Following her parents' divorce when she was six years old, Aguilera, her younger sister Rachel, and her mother (who later remarried Jim Kearns and gave birth to one more child, Michael 'Mikey' Kearns), moved into her grandmother's home in the Pittsburgh suburb of Rochester, Pennsylvania. After several years of being estranged, Aguilera expressed interest in reconciling with her father in 2012. Growing up, Aguilera, known locally as "the little girl with the big voice", aspired to be a singer, singing in local talent shows and competitions. She won her first talent show at the age of 8, in which she performed Whitney Houston's "I Wanna Dance with Somebody (Who Loves Me)". In 1990, she appeared on Star Search singing "A Sunday Kind of Love", and was eliminated during the semi-final rounds. She later performed the same song during an appearance on Pittsburgh's KDKA-TV's Wake Up with Larry Richert. Throughout her youth in Pittsburgh, Aguilera sang "The Star-Spangled Banner" before Pittsburgh Penguins hockey, Pittsburgh Steelers football, and Pittsburgh Pirates baseball games, in addition to the 1992 Stanley Cup Finals. She attended Rochester Area School District in Rochester and Marshall Middle School near Wexford, and briefly attended North Allegheny Intermediate High School before being home schooled due to bullying. In 1991, Aguilera auditioned for a position on The Mickey Mouse Club, although she did not meet its age requirements. She joined the television series two years later, where she performed musical numbers and sketch comedy until its cancellation in 1994. Her co-stars included Ryan Gosling, Keri Russell, Britney Spears, and Justin Timberlake. When she was fourteen, Aguilera recorded her first song, the duet "All I Wanna Do" with Japanese singer Keizo Nakanishi. She later sent her cover version of Houston's "Run to You" to Walt Disney Pictures in hopes of being selected to record the theme song "Reflection" for their animated film Mulan (1998). "Reflection" peaked at number 19 on the U.S. Billboard Adult Contemporary Chart.
