The Fizz are a British pop music group formed in 2004 as a spin-off from the original group, Bucks Fizz. The core of the group consists of Cheryl Baker, Mike Nolan and Jay Aston, who are all former members of Bucks Fizz and performed as OBF (Original Bucks Fizz) initially with Shelley Preston and then replaced by Jay Aston. The group then performed as Formerly of Bucks Fizz, and Bobby McVay later became a member in 2015, making the group a quartet, and then renaming as The Fizz until he left in 2018. To date, the group have released four albums, three of which have charted in the Official UK Albums Chart. Their 2017 album The F-Z of Pop reached No.25, becoming the highest-charting Bucks Fizz related album in 33 years. In 2018, Christmas with the Fizz was released. In 2020, Smoke & Mirrors was released, reaching number 29 in the Official UK Albums Chart and number 6 on the Official Sales Chart.

In December 2004, Bobby G, Mike Nolan, Cheryl Baker and Shelley Preston reformed briefly after 15 years apart to be part of 'The Here and Now Tour' of the UK.^[1] To distinguish this line-up from G's other group, they renamed themselves The Original Bucks Fizz (although Preston was not in the original four, she was the only other member to have been in a recording contract with chart success whilst in the group). Due to prior commitments with the current lineup of the group, G could not make all of the dates played, but did appear at some shows. Following this, Nolan, Baker and Preston subsequently performed more shows together as a three-piece under the same title and featured in the Congratulations show, the 50th Anniversary of the Eurovision Song Contest in Copenhagen. In September 2008, Preston, Baker, Nolan and Aston reunited for a makeover show Pop Goes the Band for Living TV, which was screened in March 2009.

In April 2009, Preston left The Original Bucks Fizz. Soon after it was announced that original member Jay Aston would be joining Baker and Nolan in the group for live shows — the first time she has been a part of Bucks Fizz since 1985.^[2][3][4] In October 2009, this line-up embarked on their first tour, encompassing 10 venues across the UK as well as a special gig at Newcastle to commemorate the 25th anniversary of their coach crash.^[5] The group released their debut single on 24 May 2010, which was a jazz-style reworking of their hit "I Hear Talk".^[6] In January 2011, while preparing for a 30th anniversary tour, The Original Bucks Fizz became caught up in a legal conflict with Bobby G over the use of the Bucks Fizz name. Baker, Nolan and Aston sought legal advice over the matter.

A mini 30th Anniversary tour took place in May 2011, while a larger scale gig took place at the London Palladium on 11 July 2011 to celebrate their 30 years. The group also recorded their debut album, Fame & Fortune?, which was a new studio album comprising six reworked Bucks Fizz tracks along with six original tracks composed by the group. The first of these, "This Day is Mine" was premiered at the May gigs and was also played on BBC Radio.^[7] The release of the album was put on hold until after the court case verdict.

A hearing between The Original Bucks Fizz and Bobby G took place on 15 July 2011.^[8] On 22 August 2011 the judge found in favour of G with the reasoning that since his wife (Heidi Manton, also a member of his group) owned the Bucks Fizz name, the use of the name The Original Bucks Fizz was an impediment on their trademark.^[9] The Original Bucks Fizz sent an appeal to the high courts but was subsequently dropped.
