Background: Nina Tucker is a fictional character from the Australian soap opera Neighbours, played by Delta Goodrem. She made her first screen appearance during the episode broadcast on 11 June 2002. Goodrem was approached by producers after they saw her video for her debut single. Goodrem, who had just signed a record deal, almost turned down the role of Nina as she felt the character did not suit her style of music.
Context: Nina was initially meant to be a "bad girl", but the writers rewrote the part for Goodrem, and the character became a "painfully shy schoolgirl" who gets a job in the Coffee Shop. The Age described Nina as the "quintessential girl next door". Goodrem described her character as "a quiet, unassuming type of girl", who did not think anything of her amazing gift. When Goodrem was asked if she was similar to Nina, she replied "I think I am in some ways and in some ways I'm not. Nina's very shy, I really like the character Nina but I think she'd probably walk out of a room and I'd probably chat all day I think that's probably the difference, she'd sneak out of a room and I'd stay!" The BBC agreed with Goodrem and said that Nina would not say "boo to a goose" and would flee if anyone looked her way. In 2003, Nina's mother, Trixie (Wendy Stapleton), arrived in Erinsborough after Nina's father, Nick, ended their relationship. Nina was upset to learn about her parents split and went into denial. She believed that they would get back together. Trixie was a professional singer and, during a set at Lou's Place, started to lose confidence, so Nina helped her out and saved the night. Stapleton stated that Nina and Trixie's relationship was complicated, and there were issues between them. Nina saw Trixie as an embarrassment, but she helped her out because she saw how sad her mother was. Stapleton explained more about Nina's early life saying, "Nina's life has been almost a gypsy one - living out of a suitcase while her parents toured. She's learned to be independent from an early age, though Trixie idolises her." Nina retreated into books and her imagination instead of being worldly from the travelling she has done. Stapleton and Goodrem did not get a chance to explore their respective character's relationship much further, as Goodrem was diagnosed with Hodgkin's lymphoma three weeks into the storyline. Scripts were changed so Nina was not directly involved and she was only mentioned by other characters. When she returned in 2004, Nina was no longer shy and vulnerable. She had taken control of her life and became more assured. Goodrem welcomed her character's development and said Nina came back strong and confident. She also said: "I think she had to grow up. If she didn't come back a little bit older and wiser, then she wouldn't have learnt and grown from what's gone on in the year that she's been missing."
Question: How did they change it?
Answer: the character became a "painfully shy schoolgirl" who gets a job in the Coffee Shop.

Background: The Four Seasons is an American rock and pop band that became internationally successful in the 1960s and 1970s. Since 1970, they have also been known at times as Frankie Valli and the Four Seasons. In 1960, the band known as the Four Lovers evolved into the Four Seasons, with Frankie Valli as the lead singer, Bob Gaudio (formerly of the Royal Teens) on keyboards and tenor vocals, Tommy DeVito on lead guitar and baritone vocals, and Nick Massi on electric bass and bass vocals. The legal name of the organization is the Four Seasons Partnership, formed by Gaudio and Valli taken after a failed audition in 1960.
Context: Frankie Valli's first commercial release was "My Mother's Eyes" (as Frankie Valley) in 1953. The following year, he and guitarist Tommy DeVito formed The Variatones (with Hank Majewski, rhythm guitar, Frank Cattone, accordion, and Billy Thompson, drums), which between 1954 and 1956 performed and recorded under a variety of names before settling on the name The Four Lovers. The same year, the quartet released their first record, "You're the Apple of My Eye", which appeared on the Billboard Top 100 singles chart, peaking at #62. Five additional Four Lovers singles (on RCA Victor) were released over the next year, with virtually no sales, airplay, or jukebox play. In 1957, the band's seventh single (this time on Epic) had a similar lack of success. From 1956 until 1958, the band stayed together, performing in clubs and lounges as the Four Lovers and recording on various record labels with various names: Frankie Tyler, Frankie Valley, Frankie Valley and the Travelers, Frankie Valley and the Romans, the Village Voices, and the Topics are some of the 18 "stage names" used individually or collectively by the members of the band. In 1958, Charles Calello replaced Nick Massi on bass in the lineup. In 1959, the band started working with producer/songwriter Bob Crewe, primarily for session work (Crewe wrote "I Go Ape", which Valli recorded with the intention of releasing it as a "solo" single). Later that year, the Four Lovers were performing in Baltimore on the same stage as the Royal Teens, who were riding the wave of success of "Short Shorts", a song co-written by then-15-year-old Bob Gaudio, who was also the Royal Teens' keyboardist. In late 1959, Gaudio was added to the Four Lovers on keyboards and guitar, as a replacement for rhythm guitarist Hank Majewski. Early the following year, Nick Massi returned to replace Calello, who remained the band's musical arranger. In 1960, despite the changes of personnel, the fortunes of the Four Lovers had not changed--they failed an audition for a lounge at a Union Township, Union County, New Jersey bowling establishment. According to Gaudio, "We figured we'll come out of this with something. So we took the name of the bowling alley. It was called the Four Seasons." Despite the last few years of frustration of the Four Lovers, this proved to be the turning point for the band. Later, on a handshake agreement between keyboardist/composer Bob Gaudio and lead singer Frankie Valli, the Four Seasons Partnership was formed.
