When they're not saving lives and improving the wellbeing of their patients, the medical staff at Lewisham and Greenwich National Health System (NHS) performs as a musical group. The NHS Choir, comprised of doctors and nurses in southeast London, formed in 2013.
Some of their members are renowned medical surgeons who travel the world to help war veterans. Other choir members face life-threatening medical diseases, including MS and cancer.
Despite their hardships, this choir records their own original Christmas song every year for charity.
Their 2015 song, entitled "A Bridge Over You", is a combination of Simon and Garfunkel's "A Bridge Over Troubled Water" and "Fix You" by Coldplay.
The incredible charity song by the NHS Choir went viral thanks to a clever social media campaign.
The NHS Choir eventually gained the attention of recording artist Justin Bieber.
Although his song 'Love Yourself' was at the top of the U.K. music charts, Bieber pleaded with his fans for a special request for Christmas week.
He asked his Beliebers to give the NHS choir the number one spot on the U.K. music charts.
"Wow. I'm speechless. It's amazing that he's come through and he's pledged his support for such good causes," said Dr. Harriet Nerva of Hinchinbrooke Hospital to Metro. "I think staff will light up inside. He's one of the biggest stars in the world and for him to support the NHS like this is a fabulous thing."
The NHS Choir soundly defeated Justin Bieber in the U.K. charts for Christmas week. Bieber's song had 97,000 downloads, and the NHS Choir had 127,000.
Bieber congratulated the NHS Choir on their success.
