This was later revealed to be a 50/50 deal that sees all profits, except publishing, split between Universal and McFly, including money from touring, record sales, merchandise and sponsorship.

On 9 July 2010, Fletcher and Poynter confirmed on Twitter that the first single from the album would be called "Party Girl", which was written in Atlanta with Austin.

The song premièred on 14 July on Radio 1 and a one-minute-long clip was posted on McFly's Myspace page.

The sixteenth century manor house featured in a number of scenes is Bruce Castle Museum in Tottenham, London; the church is the 14th century All Hallows Parish Church, just to the north of Bruce Castle.

[5] Nick Levine of Digital Spy gave the single a rating of five out of five stars, calling it "an unstoppable post-GaGa dance-pop stomper built on a deliciously fizzy mix of synths and guitar riffs", and felt that "the whopping great 'woah woah' chorus is as hard to resist as an apple pie left to cool by an open window".

The song appears in Episode 18, Series 1 of US teen drama Pretty Little Liars when the girls are attending a college frat party.
