Sometimes it is fun, while the song's playing, to think about the chain of events that led to it being picked as the new (in parts amazing) album's lead single instead of a brilliant track like 'In The Morning' or 'Wonderful Life'. Imagine the meeting at the record label.
The whole thing is just hilarious.
Anyway here is a video of Gwen performing the song at the AMAs. All that's missing is the laughter track.
(FYI the Electro Bashment mix is quite good.)
