During 2003, Charlie met fellow songwriter-guitarist Alex Westaway and drummer Omar Abidi at a party. He was by this stage becoming increasingly frustrated by the music he was performing in Busted and stated he had "all of this creativity pent up inside and I just needed to vent it somewhere, and I was writing a lot of songs but I couldn't play them, because I didn't have anyone to play them with". During the aforementioned party, an impromptu jam session took place. Simpson, Westaway, and Abidi played Rage Against the Machine's song "Killing in the Name" on loop, and agreed to attend a gig a few days later. After the show, they went back to Simpson's flat and began performing on guitars and a v-drum kit, which led to their first song being written, titled "Too Much Punch". Westaway later invited bassist Dan Haigh to practice with the band and soon began booking regular rehearsal sessions together, under the name Fightstar.
