From NetFlix:

Big energy threatens to move in and disrupt life in the small English
mining town of Grimley, but its brass band conductor refuses to hang
up his baton. Recognizing Grimley’s last chance to shine, Danny
( Pete Postlethwaite) perfects his band for their last chance at national
competition. Gloria (Tara Fitzgerald) tries to perform flawless flugelhorn
as she wrestles resentment for her part in the mine’s closure and falls
for Andy (Ewan McGregor).

Similar to Full Monty. Feel-good. Even my mom would like this one.
As I recall, OK for kids.
