Music only
Most of Britten's contributions appear in Act I, and the other incidental music consists of orchestrations of various classical, popular and traditional pieces by the musical director of the first production, Ernest Irving. In the original programme Britten acknowledges 'Geraldo' in the orchestration of 'The spider and the fly' dance. The scene in question is set in a night club, hence the 'authentic' orchestration of the number.
Musical ideas employed in both the 'Entrance of examiners' (Act I no. 9) and the 'Incinerators' ballet' (Act I no. 19) were re-used by Britten in variation 3 of Diversions, op. 21.
