In January 2004, Hamilton announced she wanted to take a hiatus from the group and devote more time to her young son. Atomic Kitten released the double A-side single Someone like Me/"Right Now 2004" as a "goodbye" to their fans, but were reunited on Valentine's Day 2005 to release the charity single "Cradle 2005", a new version of the original song from their album Right Now which was a number-one hit in Asia back in 2000. "Cradle 2005" peaked at number ten, selling 35,000 copies worldwide, with proceeds going to World Vision. In 2005, Atomic Kitten were featured on the soundtrack of Disney's Mulan II with the song "(I Wanna Be) Like Other Girls". In 2005, they also performed together in Krakow on 28 August at the Coca-Cola SoundWave Festival. In 2006, they released a cover version of The Farm song "All Together Now". It became a charity single for the 2006 FIFA World Cup and was released only in German-speaking countries. It peaked inside the German Top 20. The group reunited in December 2006 for The Nokia New Year's Eve Music Festival, performing in Hong Kong on 31 December 2006. They once again reunited to perform at The Number One Project at the Liverpool Echo Arena on 19 January 2008, which celebrated Liverpool's year as European Capital of Culture and the fact that Liverpudlian artists have had a collective 56 UK number-one singles. Also to mark the event, in the same month the group released a cover of "Anyone Who Had a Heart", which peaked at number 78 on the UK Singles Chart. Although a reunion was due to surface after reuniting in 2008, it never materialised and the girls continued with solo projects: Hamilton gave birth to her third son Alfie in June 2010, Frost presented the first four series of Snog Marry Avoid?, and McClarnon presented Hotter Than My Daughter and also appeared at the Liverpool Empire in December 2012 alongside Coleen Nolan in Cinderella.

Klaus revealed in an earlier interview on TV that the character was a caricature of Whitfield Crane, info confirmed later by its author Moish Brenman (Whitfield's high school friend and Roger Lahr's roommate in their teenagehood). Moish became the genius painter for customisation skateboards and was involved in plenty of projects about Arts. He died during the Stairway to Hell sessions and was replaced by Daniel Mercer for the coverdesigns. The UKJ he created is a boy showing a middle finger and hiding a bottle of beer behind his back, wearing a blue baseball hat, a dirty white T-shirt, green Bermuda shorts, white socks and Doc marten shoes ( or sometimes sneakers too). Moish was supposed to be the official and unique drawer of the band once they were signed by Mercury Records, but for still unexplained reasons he was replaced by Marc Goldstein (so damn cool and Goddamn Devil pictures). Some unknown pictures from Brenman about UKJ are still in existence. In a conversation on the UKJ forum in 2006, he revealed he wanted to build up a bunch of other characters deriving from the other band's members or their friends by the time he was the official drawer but that project has never been broacasted. Plenty of pictures of the UKJ are made for free for the UKJ fans. They are coverdesigns bootlegs to replace those which are disappointing (Goddamn Cool or As ugly as it gets for instance) or for old or new bootlegs without sleeves. The very great majority of those sleeves are made by UKJ Fan Artists or Mercer-Moish's fans such as Karaokeman (who is more a customizer of other artists work), Kiplegends (Iamthewolf), Marcos Moura, Vivien Hup for the most current. Those pictures are not for lucrative activities and made as a tribute to Brenman or Mercer or for fun for fans and a warning message is always put on every bootleg about the consequences if that rule of 'NOT FOR SALE' would not be respected.

Where did the character appear?
