They experienced several line-up shuffles during their existence, with Joe Baccini (bass), Sean Corrigan (guitar) and Chris (Chas) Wade (drums) playing with the group at various times. A cover version of "Why Do Fools Fall In Love" failed to produce mainstream success and 1966 saw them without a record contract.
Mick Clark left to play with The Tremeloes for a while and introduced them to a song from The Symbols act, "Silence Is Golden". He then returned to the Symbols.
Ed Kassner at President needed a harmony band to cover "See You In September" which he owned and which was a hit in the US, so The Symbols were signed. The record didn't sell, partly due to distribution problems, but it set the band up for more singles including "Bye Bye Baby" which was later to produce success for the Bay City Rollers and "Best Part Of Breaking Up", which became their second chart hit at number 25 in January 1968.
The band carried on until 1972. Mick Clark joined The Rubettes, Chas Wade and John Milton played with the pub-rock band JJ Foote during the mid-70s.
