Arnold lost interest in the band and chose to leave to become a physician; he was replaced by Chris White. After winning a beat-group competition sponsored by the London "Evening News", they signed a recording contract with Decca and recorded their first hit, "She's Not There". It was released in mid-1964 and peaked at number 12 in the UK, becoming their only UK Top 40 hit. The tune began to catch on in the United States and eventually climbed to number 2 in early December. It sold over one million copies, and was awarded a gold disc by the RIAA.
