London, UK - Pop star Justin Bieber wants to climb to the top of the British Christmas charts with the help of a choir made up of National Health Service (NHS) staff.

The remix of Bieber's single Holy, accompanied by voices from the NHS choir, is scheduled for release on December 18, British media reported on Monday.

Bieber has a history with the choir enthusiasts from the NHS hospitals in Lewisham and Greenwich. In 2015, they competed for number 1 in the Christmas charts and eventually reached the top thanks to Bieber's support.

Back then, the Canadian pop star called on his fans to support the charity choir and their song A Bridge Over You, which finished ahead of Bieber's own acoustic hit, Love Yourself.

The proceeds of this year's co-production will be donated to charitable organizations of the NHS.

Lizzie Farrant, a member of the choir, told PA media: “All that time we have managed to keep virtual rehearsals together. We have really given ourselves the support, and then for [Justin Bieber] to get in touch and say, ‘I would really like to do this collaboration and share this with you’… that’s really fantastic.”
