Its original members comprised Jomo Baxter, Jayde Spence, Ryan Elliott, Nick Grant and the then 9 years old Haydon Eshun.
In 1992, the band were originally known as Chaos, but their only single issued under this name was a cover version of the Michael Jackson song "Farewell My Summer Love".
The Ultimate Kaos fanbase spread into Europe and brought them hits in Germany, Austria, Sweden, France and Belgium.
On 20 October 1994, during the height of their success, they were featured on BBC Television's Top of the Pops, when their average age, as a band, was fourteen.
Eshun released a solo album titled Justice in 2009 and is currently appearing in the West End stage musical Thriller – Live in London.
