BBC Sport - Six Nations 2014: BBC Wales teaches fans Calon Lân

Six Nations 2014: BBC Wales trail

Wales kick off their Six Nations campaign against Italy on February 1 aiming to become the first side to win three titles in a row.

BBC Cymru Wales' trail for the 2014 campaign aims to have the nation singing the hymn and rugby anthem Calon Lân (which translates as "A Pure Heart").

It is performed in schools and by choirs throughout the nation - but how many people remember the words?
