Frozen: Let It Go as you've never heard it before

As part of anti-bullying week one school in West Yorkshire emailed us to share their new version of Let It Go from the film Frozen.

They've changed the lyrics to be all about bullying - from "Let It Go" to "Let Them Know".

Teacher Mr Clifford said: "The words in the song make it clear how important it is to let somebody know if you feel like you are being bullied."

Sing along to Let Them Know
