As the nation's favourite weekly music show moves towards the end of the 90s, pop has a resurgence after Britpop's peak, and girl groups are still taking centre stage.Step forward two quartets with sisters and friends at their hearts: All Saints, with their cool grooves and cargo pants, and Irish four-piece B*Witched, who in 1998 became the youngest girl group to have a number one with C'est La Vie. Robbie Williams continues his solo rise to fame, and the Euro factor took a cool turn with French duo Air creating a new 90s sound with their chilled laidback electronica. It was also a big year for sport, with a World Cup dominating the summer, a football anthem or two hitting the charts and a certain Vindaloo causing chaos in the Top of the Pops studio.Contributors include All Saints, Edele Lynch and Lindsay Armaou of B*Witched, Nicolas Godin and Jean-Benoît Dunckel of Air, Keith Allen, Trevor Nelson, Guy Chambers and Justin Currie of Del Amitri.
