Plot
As well as being the title of the show, Britain's Got The Pop Factor... And Possibly A New Celebrity Jesus Christ Soapstar Superstar Strictly On Ice is the title of the fictional series the show is based around. Kay stars as a fictional contestant on the show, singer Geraldine McQueen. Nicki Chapman, Pete Waterman and Neil Fox (who were also judge panellists in Popstars and Pop Idol respectively) starred as judges.[2] Jo Enright, Karl Lucas, David Hulston and Sian Foulkes performed as a band, Two Up Two Down, in which the two women are wheelchair users.[2] Cat Deeley is "the host" of the show.[3]
R(Our) Wayne sang a medley of Return to Innocence by Enigma, Love Train by Kenny Gamble and Leon Huff, Earth Song by Michael Jackson, YMCA by The Village People and There's No-one Quite Like Grandma by the St Winifred's School Choir.
Two Up Two Down sang a medley of We Built This City by Starship, Bootylicious by Destiny's Child, 9 to 5 by Dolly Parton, Holding Out For A Hero by Bonnie Tyler and Hero by Mariah Carey.
Geraldine sang a medley of Born To Run by Bruce Springsteen, the theme to Born Free (perhaps best known as Andy Williams' version), Free Nelson Mandela by Special AKA, Umbrella by Rihanna, C'est La Vie by B*witched and Milkshake by Kelis.
Guest Stars
The show featured cameo appearances from:
* Sir Paul McCartney * The Cheeky Girls * Ricky Wilson * Rick Astley * Lionel Blair * Rustie Lee
The second part wasn't as funny as the first part, but it still had some funny bits.
Like the conjoined twins coming in at the end, one singing and the other reading a book, or Two Up Two Down singing suicide is painless to the young girl in a wheelchair at her birthday party.
The auditions in the first part were very funny, the guy who's dog just laid down until he realised he brought the wrong dog, or the two guys, one with a eye patch and the other with an electronic voice box singing Bon Jovi.
Peter Kay singing the theme from home and away with Paul McCartney, Lionel Blair teaching dancing and the cheeky girls giving singing advice.
Shame the real shows it was mocking aren't this good.
