The tune is named after Blaenwern Farm near Tufton, Pembrokeshire, where Rowlands sent his son from Porth to stay with friends of the family to convalesce as it was thought the fresh air would assist his recovery: he named the tune in honour of them.
In the United Kingdom Blaenwern has come to be used as the prevalent setting for the hymn Love Divine, All Loves Excelling,[1] but also in other settings including the Welsh Deued Dyddiau O Bob Cymysg by William Williams Pantycelyn, and Calon Lân by Daniel James.
It also became familiar to a wider audience through the Billy Graham crusades when it was used as a setting to What a Friend We Have in Jesus.
As a setting for Love Divine it is a popular choice at English weddings and was voted as one of Britain's ten favourite hymns in October 2005.
[2] Love Divine, All Loves Excelling, set to Blaenwern, was sung at the wedding blessing of Prince Charles and Camilla Parker-Bowles and it was also selected as one of three hymns sung at the wedding of Prince William and Catherine Middleton,[3] the others being Guide Me, O Thou Great Redeemer, set to Cwm Rhondda, and Jerusalem.
