Some context: George Michael Cohan (July 3, 1878 - November 5, 1942), known professionally as George M. Cohan, was an American entertainer, playwright, composer, lyricist, actor, singer, dancer and producer. Cohan began his career as a child, performing with his parents and sister in a vaudeville act known as "The Four Cohans." Beginning with Little Johnny Jones in 1904, he wrote, composed, produced, and appeared in more than three dozen Broadway musicals. Cohan published more than 300 songs during his lifetime, including the standards "Over There", "Give My Regards to Broadway", "The Yankee Doodle Boy" and "You're a Grand Old Flag".
From 1899 to 1907, Cohan was married to Ethel Levey (1881-1955; born Grace Ethelia Fowler), a musical comedy actress and dancer. Levey and Cohan had a daughter, actress Georgette Cohan Souther Rowse (1900-1988). Levey joined the Four Cohans when Josie married, and she starred in Little Johnny Jones and other Cohan works. In 1907, Levey divorced Cohan on grounds of adultery.  In 1908, Cohan married Agnes Mary Nolan (1883-1972), who had been a dancer in his early shows; they remained married until his death. They had two daughters and a son. The eldest was Mary Cohan Ronkin, a cabaret singer in the 1930s, who composed incidental music for her father's play The Tavern. In 1968, Mary supervised musical and lyric revisions for the musical George M!. Their second daughter was Helen Cohan Carola, a film actress, who performed on Broadway with her father in Friendship in 1931. Their youngest child was George Michael Cohan, Jr. (1914-2000), who graduated from Georgetown University and served in the entertainment corps during World War II. In the 1950s, George Jr. reinterpreted his father's songs on recordings, in a nightclub act, and in television appearances on the Ed Sullivan and Milton Berle shows. George Jr.'s only child, Michaela Marie Cohan (1943-1999), was the last descendant named Cohan. She graduated with a theater degree from Marywood College, Scranton, Pennsylvania, in 1965. From 1966 to 1968, she served in a civilian Special Services unit in Vietnam and Korea. In 1996, she stood in for her ailing father at the ceremony marking her grandfather's induction into the Musical Theatre Hall of Fame at New York University.  Cohan was a devoted baseball fan, regularly attending games of the former New York Giants.  He died of cancer at the age of 64 on November 5, 1942, at his Manhattan apartment on Fifth Avenue, surrounded by family and friends. He received his last rites from Mgr. John J. Casey, representing Archbishop Francis Spellman, and Rev. Francis X. Shea, vicar of the Archdiocese of New York. His funeral was held at St. Patrick's Cathedral, New York and was attended by thousands of people, including five governors of New York, two mayors of New York City and the Postmaster General. The honorary pallbearers included Irving Berlin, Eddie Cantor, Frank Crowninshield, Sol Bloom, Brooks Atkinson, Rube Goldberg, Walter Huston, George Jessel, Connie Mack, Joseph McCarthy, Eugene O'Neill, Sigmund Romberg, Lee Shubert and Fred Waring. Cohan was interred at Woodlawn Cemetery in The Bronx, New York City, in a private family mausoleum he had erected a quarter century earlier for his sister and parents.

Some context: Isaac Hayes, Jr. was born in Covington, Tennessee, in Tipton County. He was the second child of Eula (nee Wade) and Isaac Hayes, Sr. After his mother died young and his father abandoned his family, Isaac, Jr., was raised by his maternal grandparents, Mr. and Mrs. Willie Wade, Sr. The child of a sharecropper family, he grew up working on farms in Shelby County, Tennessee, and in Tipton County.
In 1995, Hayes appeared as a Las Vegas minister impersonating himself in the comedy series The Fresh Prince of Bel-Air. He launched a comeback on the Virgin label in May 1995 with Branded, an album of new material that earned impressive sales figures as well as positive reviews from critics who proclaimed it a return to form. A companion album released around the same time, Raw and Refined, featured a collection of previously unreleased instrumentals, both old and new. Hayes worked on the theme for the 1996 theatrical release 'Beavis and Butt-Head Do America', producing a piece which was essentially a hybrid of 'The Theme From Shaft' and the theme from the original 'Beavis and Butt-Head' TV show.  Soon after, Hayes joined the founding cast of Comedy Central's animated TV series, South Park. Hayes provided the voice for the character of "Chef", the amorous elementary-school lunchroom cook, from the show's debut on August 13, 1997 (one week shy of his 55th birthday), through the end of its ninth season in 2006. The role of Chef drew on Hayes's talents both as an actor and as a singer, thanks to the character's penchant for making conversational points in the form of crudely suggestive soul songs. An album of songs from the series appeared in 1998 with the title Chef Aid: The South Park Album reflecting Chef's popularity with the show's fans, and the Chef song "Chocolate Salty Balls" became a number-one U.K. hit. However, when the South Park movie South Park: Bigger, Longer & Uncut was released the following year, Chef was the only major character who did not perform a showcase song in the film; his lone musical contribution was "Good Love," a track on the soundtrack album which originally appeared on Black Moses in 1971 and is not heard in the movie  In 2000, he appeared on the soundtrack of the French movie The Magnet on the song "Is It Really Home" written and composed by rapper Akhenaton (IAM) and composer Bruno Coulais. In 2002, Hayes was inducted into the Rock and Roll Hall of Fame. After he played a set at the Glastonbury Festival, the same year a documentary highlighting Isaac's career and his impact on many of the Memphis artists in the 1960s onwards was produced, "Only The Strong Survive". In 2004, Hayes appeared in a recurring minor role as the Jaffa Tolok on the television series Stargate SG-1. The following year, he appeared in the critically acclaimed independent film Hustle & Flow. He also had a brief recurring role in UPN/The CW's Girlfriends as Eugene Childs (father of Toni).
