Background: Bucks Fizz are a British pop group that achieved success in the 1980s, most notably for winning the 1981 Eurovision Song Contest with the song "Making Your Mind Up". The group was formed in January 1981 specifically for the contest and comprised four vocalists: Bobby G, Cheryl Baker, Mike Nolan and Jay Aston. They achieved instant attention with the dance routine which accompanied the song, involving a skirt-rip. The group went on to have a successful career around the world (albeit ignored in the United States), while the UK remained their biggest market, where they had three No.1 singles with "Making Your Mind Up" (1981), "The Land of Make Believe" (1981) and "My Camera Never Lies" (1982) and became one of the top-selling groups of the 1980s.

Conteúdo: With Nolan recuperating during the early months of 1985, the group returned to recording and released their next single in June. However, within the group, tensions had mounted to the point that Jay Aston no longer wanted to continue. After early promotion and a concert in Newcastle, she sensationally quit the group, despite still being under contract. Again, Bucks Fizz found themselves the subject of newspaper headlines, where it emerged that Aston had been having an affair with Andy Hill -- the husband of the group's creator Nichola Martin. Aston sold her story to the press in an article headlined; "The hateful, bitchy world of Bucks Fizz", while member Cheryl Baker was keen to point out that they were never friends. Aston was sued by management over breach of contract while a replacement member was quickly sought to continue promotion for the current single. Auditions were held at The Prince of Wales Theatre, where 800 girls were seen. Eventually, 21-year-old Shelley Preston was given the job and unveiled to the press and TV among much media attention.  In early 1986, the group's contract with RCA expired and a new one with Polydor was signed. The first single, "New Beginning (Mamba Seyra)" was released in May and brought the group back to prominence as it became a top 10 hit and one of their most successful singles. After two more less-successful singles and an album, the group took a break during 1987 and regrouped in 1988. After a successful UK tour, the group released
