The NHS Choir continues to lead way in the race for this year's Christmas Number 1, Official Charts can confirm.
The race is far from over yet though, as their lead on yesterday's update over Justin Bieber's Love Yourself (which was based on sales only) has reduced to just over 2,000 combined sales and streams.
Bieber's previous single, Sorry, has also climbed back up to complete the Top 3.
The Lewisham & Greenwich NHS Choir's A Bridge Over You - a mash-up of Coldplay's Fix You and Bridge Over Troubled Water by Simon & Garfunkel - is being released in support of the NHS, with proceeds going to charities Mind and Carers UK.
Meanwhile, fellow contender Stormzy climbs with his bid for Christmas Number 1 Shut Up, which climbs from 8 to Number 7. A clearer picture of where all of this year's contenders are will emerge in tomorrow's Official Chart Update (December 21), but in the meantime, you can check out this year's contenders list in full here.
Sales and streams of songs between 00.01am on Friday, December 18 and midnight on Thursday, December 24 will count towards the 2015 Official Christmas Singles Chart.
The Official Christmas Singles Chart Top 40 will be counted down on BBC Radio 1’s Official Chart Show with Greg James between 10am - 1pm on Friday, December 25, and also revealed on BBC One's Top of the Pops. The full Top 100 will be revealed on OfficialCharts.com at 5.45pm. More info here.
