Why the Welsh sing hymns
This weekend Twickenham and pubs and rugby clubs all over Wales will once again be ringing with renditions of Calon Lan and Cwm Rhondda as Wales take on South Africa in the Rugby World Cup.
The Welsh are known for hymns but these days it is often fuelled more by alcohol than the fire and brimstone sermons of the chapels that first introduced them.
While chapel may largely be a thing of the past, it would be a mistake to underestimate how much it is branded into Welsh culture.
And never more so than during a game of rugby.
