Produced by Greg Wells and Engineered by Drew Pearson, it was released as the album's lead single on 18 August 2007 as a digital download.
The down-tempo, electropop-dance song, is a change in direction from the pop rock sound from their previous album, The Secret Life Of... (2005).
[1] The composition was influenced by the electropop of underground bands in Los Angeles, whose sound the Veronicas were keen to incorporate into their own music.
[1][11] It was certified platinum by the Australian Recording Industry Association (ARIA), denoting 70,000 copies shipped in Australia.
[15] The Veronicas pushed for a school revolt storyline to the music video's director Scott Speer,[16][17] after a concept which would "sex up [Lisa and Jessica]" was first presented to them.
They're free" [...] Because the song is so different from the first record, we wanted to make a video that was young and fun that kids could relate to.
It then cuts to two separate lines of male and female students, the latter being led by Lisa and Jessica, marching down a school corridor.
When the chorus begins, Lisa and Jessica are standing on a stage in front of their band performing for rows of still students who stare back blankly.
When the second verse begins the students are in the classroom while guards patrol its perimeter and the teacher hits a blackboard with a pointing stick.
When the bridge starts smash cuts are shown of them taking over the school's PA system, and the students getting up from their chairs in the classrooms and throwing objects at a teacher standing in front of a blackboard.
[20] Clothed in costumes similar to the music video, Lisa and Jessica appeared from a yellow school bus.
[21] During the performance Lisa and Jessica sang vocals, while the latter also played the electric guitar, with their band, as opposed to using synthesised instruments in the original recording.
