Terrence P. Melcher (February 8, 1942 - November 19, 2004) was an American musician and record producer, who was instrumental in shaping the sound of American West Coast rock music. His greatest contribution to the culture of the time was producing The Byrds' innovative hits "Mr Tambourine Man" and "Turn! Turn! Turn!" and his groundbreaking work with the Beach Boys. He was the only child of actress/singer Doris Day.

Melcher was born Terrence P. Jorden in New York City to trombonist Al Jorden and his wife, singer-actress Doris Day, who was only 17 at the time. Known as Terry, the boy was named by his mother after the hero of her favorite childhood comic strip, Terry and the Pirates. Before the birth, Day was planning to leave the abusive, violent Jorden. Outraged when he found out about her pregnancy, Jorden had demanded that Day get an abortion. Shortly after giving birth, Day filed for divorce, left the boy with her mother in Ohio, and went back to touring with big band leader Les Brown. After the divorce, Jorden visited his son infrequently and had little presence in his life.

Sharon Marie Tate (January 24, 1943 – August 9, 1969) was an American actress. During the 1960s she played small television roles before appearing in several films. After receiving positive reviews for her comedic performances, she was hailed as one of Hollywood's promising newcomers and was nominated for a Golden Globe Award for her performance in Valley of the Dolls (1967). She also appeared regularly in fashion magazines as a model and cover girl.

Married to film director Roman Polanski in 1968, Tate was eight and a half months pregnant when she was murdered in her home, along with four others, by followers of Charles Manson.

A decade after the murders, Tate's mother, Doris, in response to the growing cult status of the killers and the possibility that any of them might be granted parole, organized a public campaign against what she considered shortcomings in the state's corrections system. It resulted in amendments to the California criminal law in 1982, which allowed crime victims and their families to make victim impact statements during sentencing and at parole hearings.

Charles Milles Manson (born November 12, 1934) is an American criminal who led what became known as the Manson Family, a quasi-commune that arose in California in the late 1960s. He was found guilty of conspiracy to commit the Tate/LaBianca murders carried out by members of the group at his instruction. He was convicted of the murders through the joint-responsibility rule, which makes each member of a conspiracy guilty of crimes his fellow conspirators commit in furtherance of the conspiracy's objective.

Manson believed in what he called "Helter Skelter," a term he took from the song of the same name by The Beatles. Manson believed Helter Skelter to be an impending apocalyptic race war, which he described in his own version of the lyrics to the Beatles' song. He believed his murders would help precipitate that war. From the beginning of his notoriety, a pop culture arose around him in which he ultimately became an emblem of insanity, violence and the macabre. The term was later used by Manson prosecutor Vincent Bugliosi as the title of a book he wrote about the Manson murders.

Doris Day (born Doris Mary Ann Kappelhoff, April 3, 1924) is an American actress, singer, and animal rights activist. With an entertainment career that spanned through almost 50 years, Day started her career as a big band singer in 1939, but only began to be noticed after her first hit recording, "Sentimental Journey", in 1945. After leaving the Les Brown & His Band of Renown to try a solo career, she started her long-lasting partnership with Columbia Records, which would remain her only recording label. The contract lasted from 1947 to 1967, and included more than 650 recordings, making Day one of the most popular and acclaimed singers of the 20th century. In 1948, after being persuaded by Sammy Cahn, Jule Styne and her agent at the time, Al Levy, she auditioned for Michael Curtiz, which led to her being cast in the female lead role in Romance on the High Seas.

With a legendary Hollywood "girl next door" image, and capable of delivering comedy and romance as well as heavy drama, she appeared in 39 films, released 29 albums, spent 460 weeks in the Top 40 charts and eventually became one of America's most beloved entertainers. She received an Academy Award nomination for her performance in Pillow Talk, won three Henrietta Awards (World Film Favorite), a Grammy Lifetime Achievement Award, Presidential Medal of Freedom, Legend Award from the Society of Singers, Los Angeles Film Critics Association's Career Achievement Award and, in 1989, received the Cecil B. DeMille Award for lifetime achievement in motion pictures.

Sweet Baby (originally known as Sweet Baby Jesus) was a pop punk band that originated from Berkeley, California, and was part of the 924 Gilman Street scene. They were signed to Ruby Records.

Formed in 1986 by singer Dallas Denery and singer/guitarist Matt Buenrostro with Crispy Jim (later of The Saddlebacks) on bass and Dr. Frank (the frontman of The Mr. T Experience) on drums. Frank and Crispy Jim did not appear on any Sweet Baby recordings, having been already replaced by Sergie Loobkoff (Samiam, Knapsack) and Richie Bucher (Jüke, Wynona Ryders), respectively. Aaron Elliott aka Aaron Cometbus also played drums for them on their 1989 US tour. They had two songs on the Maximum Rock and Roll compilation Turn it Around (1988), "She's from Salinas" and "Pathetic." In 1989, they released their only lp, It's A Girl on Ruby Records (a Slash/Warner subsidiary). Lookout Records re-released it in 1995.'

In January 2005, their song, "Baby Baby Baby Baby Baby Baby Baby, I Love You" was featured on Bravo in an advertisement for the show Queer Eye for the Straight Girl.
