The bands' bus manages to evade a series of obstacles set up by the local police, and they arrive and put on the show for the BBC television cameras.
The film ends with everyone enjoying the music, including the mayor who has been easily persuaded to take the credit for having arranged a successful show.
The film predominantly comprises musical numbers, including performances by the principal actors Helen Shapiro and Craig Douglas themselves.
These jazz insets are dashing, deafening or sociologically depressing according to one's personal reaction, with Helen Shapiro's assurance (as a singer, though not yet as an actress) and the Temperance Seven's devastatingly funny impassivity making notably strong impressions.
For once it is sheer zest and invention which count, for they are the qualities – far more than the jamboree of topline "pop" artists taking part – which have succeeded in turning a basically threadbare, trashy plot-line into a genuinely comic occasion.
