"Calon Lân" is a Welsh hymn, the words of which were written in the 1890s by Daniel James (Gwyrosydd) and sung to a tune by John Hughes. The song was originally written as a hymn, but has become firmly established as a rugby anthem, associated with the Welsh rugby union, being sung before almost every Test match involving the Welsh national team – though more likely to be heard sung at matches involving the Welsh football team in recent years. In 2007 the song was one of the traditional Welsh songs to make it to the screen in an S4C television series Codi Canu, an attempt to bring traditional four-part harmony choral singing back to the Welsh rugby terraces.
