The story of Jimmy Rabbitte, a young working class music fan, who shapes an unlikely bunch of amateur musicians and friends into an amazing live act, the finest soul band Dublin has ever produced. The show follows the journey of two members of a frustrated synthesizer band – the opening scene we find them playing but being ignored in a shop window – who turn to Jimmy, the local music expert, for help. Placing a classified advert in a music paper, Jimmy auditions a number of wannabes before finalising the new line up who he names The Commitments. The humour kicks in as the band get to know each other and their instruments, and proceed through early rehearsals for their first gig. Just as they improve and begin to get a name for themselves they combust. The backing singers are all getting off with the middle aged horn legend, the singer has entered Eurovision and the saxophone player has dangerous leaning towards a jazz career.
