The songs are a nostalgic pastiche of 1960s music, and the story tells a tale of teenage dreams and young love "set around 1964 in a nightclub called the Club-a-Go-Go".
When they returned to England they were signed, along with Tammy Jones, by Mrs Wallich of Delyse Records to form a folk group, The Three People, and released a number of singles through EMI.
After touring Germany they split up and the brothers formed the progressive rock band The Quiet World, recruiting arranger Philip Henderson and guitarist Steve Hackett (who went on to join Genesis).
The musical was directed by Marc Urquhart and starred Binky Baker as Eric, David Easter as Gary and Terry, Lisa Hollander as Bridget, Mitch Munroe as Sharon, Georgia Mitchell as Sue, James Powell as Rick, Roy Smiles as Eddie and Debi Thomson as Penny and Shirl.
The owner of the club, ageing rocker Eric "Rubber-legs" De Vene, watches and lends an ear to the young people as they navigate the rituals of teenage fashion, music, sexual mores and relationships.
