History of the song
This popular hymn tune, originally written by John Hughes (1873–1932), is called Cwm Rhondda (the Welsh name for the Rhondda Valley) and now (quite erroneously) known as Bread of Heaven.
The text, originally Arglwydd, arwain trwy’r anialwch in Welsh, was written by William Williams and translated into English by Peter Williams in the 1771 hymnal Hymns on Various Subjects.
It is often a setting for the hymn, Wele’n sefyll rhwng y myrtwydd, by Ann Griffiths.
So, much to the surprise of many, Bread of Heaven was never intended as a song in the first place but has now become what many see as the unofficial Wales national anthem.
