Commuters were stopped in their tracks at King’s Cross - when the Sugababes burst out of a billboard to perform an impromptu gig at the station. The 90s pop trio appeared after an intrigued Londoner press a mysterious button which simply read ‘push for something sweet’ causing the band to kick start the performance of their 2005 hit, ‘Push the Button’. Onlookers admitted to missing trains to catch the show as the band was revealed from behind replica elevator doors reminiscent of the song's music video. The original trio, Mutya Buena, Keisha Buchanan, and Siobhan Donaghy put on the surprise gig to celebrate the launch of Sky Broadband’s new 24/7 switching support service. A new tongue in cheek video shows the Sugababes pitching the ‘Suga Broadband Babes’ collaboration by leveraging their nostalgic music catalogue to convince Sky bosses they’re the perfect match for the campaign.
