If you happened to be watching last night's London special of 'The Late Late Show', one moment that stood out was the beautiful performance of 'When You Were Sweet Sixteen'.

The song, which was a hit for The Fureys in 1981 with Davey Arthur, was performed on the night by Finbar Furey and Imelda May to a captive audience in the middle of London, and has already gone viral across Facebook as a result.

Finbar Furey, of course, is no stranger to 'The Late Late Show' and played a beautiful rendition of 'The Green Fields Of France' with Christy Dignam of Aslan last year.

Here's last night's song, in full.
