Music and motherhood create spiky discord in this honest, raucous and irrepressible British musical drama, which is as full of heartache and hardship as the foot-tapping Country tunes which power the story.

Irish actress Jessie Buckley won renown last year for her riveting big screen debut turn in the terrific thriller, Beast, and here she’s staggeringly great as Rose-Lynn, a Glaswegian sweary single-mum who aspires to singing stardom in Nashville.

No retiring wall flower, Rose is immature and untamed as she struggles with the harsh truths of choosing between her kids and her dreams, but her passion and vulnerability makes us root for her.

And she’s the thorn in the side of her put-upon mother, Julie Walters, who responds by giving her most affecting performance in years as she copes with her daughter’s chaos.

The grandkids are generally un-impressed by the adults except when Buckley’s extraordinary voice belts out her own compositions, as she demonstrates why this Rose is blooming marvellous.
