Scenes set both outside and inside the fictional Countess Theatre (bought by Nicky's father Hamilton Black in the film) were filmed on location at the Finsbury Park Empire Theatre. In the film, a medley of songs known as the "Vaudeville routine," framed by the song "What D'You Know, We've Got A Show", is performed by Nicky and his friends. The entire sequence was recorded in one day (9 August 1961) at the Abbey Road studios, London. While session singers – the Mike Sammes Singers – were used on the album, the film version deployed the actors.
