FANCY a sing-a-long?

Former Warrington Wolves player Gareth O'Brien appears in a charity music video raising awareness of a rare condition that affects the development of the brain.

The local lad appears singing along to I Want You Back to support the cause Reverse Rett.

A spokesman added: "Everybody who knows anything about Rett Syndrome knows that there's nothing good about it.

"It is a truly horrible, unforgiving disease but there's only so many ways to tell that story.

"This year, filmmaker Mark Elliott has created a video to describe the amazing science going on around the world and the hope we all have for the future.

"We are delighted that the leading Rett scientists from across the globe chose to take part alongside some of the girls affected by Rett, their families and friends."

The video premiered at Reverse Rett Bonfire Night 2015 which was held at OXO2 in London.
