Trio at a rock festival from the 1973 Inspector Wexford mystery novel Some Lie and Some Die by Ruth Rendell. Their set at an English rock festival is interrupted when the cops have to announce there's been a murder.
The fans began to drift back towards Sundays park, drawn by the sound of amplified guitars. The Greatheart, a three-man group, had taken the stage. Burden, listening to them, began to show his first signs of approval since the beginning of the concert. The Greatheart made a specialty of singing parodies of wartime hits, but Burden didn't yet know they were parodies and a half-sentimental, half-suspicious smile twitched his lip.
