The songs are an integral part of Blood Brothers. They are spread throughout the play. The songs are used for different reasons, including filling in gaps in the storyline, creating mood and atmosphere, revealing information about characters and reminding the audience of key themes and ideas.
The actors sing the songs live, often with a live band as well. This creates more atmosphere for the audience. Russell aimed to include songs that were reminiscent of the type of music sung in working men’s clubs, so the music helps to create a mood that is close to the types of places people like the Johnstones and their friends may have visited.
When the actors sing their songs, they remain in character throughout, as the songs are important in revealing more about what these characters are like and their thoughts and feelings. Although the songs are not a natural way for the characters to communicate, they are included seamlessly within the action of the play.
