By 1962, Chad Stuart and Jeremy Clyde had graduated from school, although Clyde was a year ahead and had gone off to Scotland seeking a theater career, thereby dissolving the band. Eventually, he returned and couldn't find acting work because of a strike, so he and Stuart reconnected and became a singing duo. Fortune would smile on them when they were able to get the attention of John Barry, a famous composer who had scored several James Bond films. "Jeremy's mother knew a literary agent who [knew] a manager — Tony Lewis — who dragged John Barry into Tina's [club] one night," Chad explained on the duo's website.

Barry, who was also a record producer, signed them on a tiny label called Ember Records in 1963. Despite being a small label with very little exposure, their Barry-produced song "Yesterday's Gone" climbed the British charts. However, Ember couldn't keep up with the major labels so Barry departed. Record producer Shel Talmy stepped in and produced their first album, "Chad & Jeremy Sing For You."

In 1964 as the British Invasion was burgeoning, the American record company World Artists signed Chad & Jeremy, and their song "Yesterday's Gone" found its way into the U.S. top 20. Subsequently, when the single "A Summer Song" was released stateside, it would become their biggest hit.
