Fletcher was originally accepted as part of Busted's line-up, but Island Records went on to reassess the situation and eventually decided to have the band as a three-piece rather than a four-piece.

Bassist Dougie Poynter and drummer Harry Judd were subsequently recruited via a classified advertisement in the NME magazine.

[2] The pair, both Essex lads, coincidentally turned up at the same audition and got to talking over their shared appreciation of the band The Starting Line, after Poynter noticed their name and logo was printed on Judd's T-shirt.

The song was later released as a regular track on the deluxe edition of the band's 2012 compilation album Memory Lane: The Best of McFly.

As Busted moved out of pure pop into more serious material, the way was left open for McFly to capture teenage girls' hearts with their debut album, Room on the 3rd Floor.

Named after the character in the Back to the Future trilogy and sounding like an updated 2000s garage band with close harmonies and raw guitars, McFly opened their album with two number one singles, "5 Colours in Her Hair" and "Obviously," so Room on the 3rd Floor really couldn't fail—and it didn't, hitting the top on its first week of release.

"That Girl," the third single released, could have sat easily on a Beach Boys album from the 1960s, or possibly even the early Beatles with the count of "one two three four" before a guitar crashes in.
