About the Characters

• Esther Caddick, played by Sarah Lancashire, is the church secretary and choir member. She is mother to Georgia, Kyle and Fred, and separated wife to the choir's conductor, Michael. Describing her character, Lancashire noted Esther has "very traditional values" and is "hugely generous". When Michael leaves her, Lancashire describes how Esther "just gets on with it" and "deals with it in the only way [she] knows how"
• Michael Caddick, played by Neil Pearson, is the husband of Esther Caddick and the respected conductor of the local choir. When Layla arrives to the town, Michael begins to question his current situation with Esther and where his life will end. He ends his marriage and begins a relationship with Layla.
• Layla, played by Sarah Alexander, is the new arrival in the town. Michael, after hearing her soprano singing voice, makes her the star attraction in the choir and forms a relationship with her in secret, later leaving Esther and his children. Alexander was immediately drawn to the character from Debbie Horsfield's scripts, and describes her as "manipulative" and "a damaged individual". Alexander does not perform her own singing scenes and instead professional Rachel Luxon was brought in to dub. It was revealed in episode 5 that Layla and Jake are siblings.
• Kyle Caddick, played by Richard Fleeshman, is son of Esther and Michael Caddick. He is musically gifted and provides much of the inspiration when Esther decides to set up her own choir. While not directly approached, it is suspected that Kyle has a form of autism along the lines of Asperger's syndrome.His guitar is usually Tom Delonge's signature Gibson ES-333.
• Jake Barton, played by Bryan Dick, is the new church curate. Dick, who has previously appeared in several television productions, relished the opportunity to be part of an ensemble piece. Although Jake appears regularly throughout the programme, he is one of few characters who are not part of the musical productions. It was revealed in episode 5 that Jake and Layla are brother and sister.
• Grace Oudidja, played by Ayesha Gwilt. Grace is the Caddick family's next door neighbour and the drummer in Kyle and Fred's band. It seems that Grace and Kyle both like each other and they both bond over their passion for Blink-182 and Kyle's knowledge of Tom DeLonge.
• Other characters include Jo Woodcock as Georgia Caddick, a keen member of the choir and daughter to Esther and Michael, Jamie Birtwhistle as Fred Caddick, son of Michael and Esther and brother to Georgia and Kyle, Clive Rowe as Clifford "Shrek" Beale, the church caretaker, and Annette Badland as Ethel Tonks, member of the choir and a promoter of rules and organisation within the church. David Fleeshman, father of Richard Fleeshman (Kyle), also appears as Ethel Tonks' husband, Gilbert "Jabba" Tonks.
