Would-be pop star Bobby has two ambitions at St Mungo's Youth Club in Essex – to make the big time and impress the local siren, the gorgeous Sue.
The first is nipped in the bud by the arrival of Norman, not the best choice of names for a teen idol but one which nevertheless gives rise to the group Norman and the Conquests.
Then, when the flash newcomer moves in on Sue, Bobby's tale of woe seems complete.
But waiting in the wings is his best mate's 15-year-old sister Laura, plain, bespectacled – and a songwriter who shows every promise of becoming the 1961 version of Cathy Dennis.
The pair team up to enter a national songwriting competition and so the tale of Dreamboats and Petticoats unfolds at Nottingham's Theatre Royal this week.
This jukebox musical by Laurence Marks and Maurice Gran is based on the best-selling albums Dreamboats and Petticoats and if the plot is slight it is an absolute joy of a show with more than 40 numbers from the pre-Beatles era performed live.
They are given a fresh lease of life by this talented cast and the uncertainties, fun and misunderstandings of being a teenager in that innocent age are brilliantly captured.
Dreamboats and Petticoats is showing at the Theatre Royal until Saturday.
