A video has been released online showing a church organist performing a beautiful rendition of David Bowie song Life On Mars on the day it was announced the rock star legend and musical icon had died at the age of 69.

The performance of the 1973 song, from the album Hunky Dory, took place at the Kelvingrove Art Gallery and Museum in Glasgow on 11 January, a few hours after it had been announced that David Bowie had passed away following an an 18-month battle with cancer.

The two-and-a-half-minute clip was posted to Facebook by Gordon Wilson, who commented underneath, "I think Bowie would have loved it. I noticed a few tears amongst the audience".

The organist performing the moving tribute in the video is believed to be Christopher Nickol, an accompanist and soloist with many of Scotland's major choirs and orchestras. He is also a regular recitalist at Kelvingrove Art Gallery and Museum.

Since being posted online the video has gone viral, being watched over 1.5m times and shared almost 40,000 times on Facebook.
