In this final look back at the 1990s, there's everything from observing the rules of certain dance routines to how the weather changed everything for Travis. Plus, US divas grace the studio in the shape of Whitney, Britney and Beyonce, the influence of Ibiza and the rise of UK garage, how a particular phrase entered the UK's vocabulary, and Top of the Pops goes on tour before a final move from Elstree back to the iconic west London BBC TV Centre.
