Push the Button - Olympic theme tune?

 Perhaps not theme tune - but this great Sugababes song was selected by Danny Boyle to help kick off the section on British pop music at the spectacular Olympics opening ceremony last night. The video has nearly 4 million views on YouTube. Guests at the event included MutyaKeishaSiobhan, spotted together in the stadium on Twitter. Artists on the video are Mutya, Keisha and Heidi.
