The tune was probably written by Robert Williams, a blind basket-maker: a copy of the tune, there called ‘Bethel’, was in the possession of his family in 1920. It is now called ‘Llanfair’, probably after Llanfair-ynghornwy near Mynydd Ithel in Anglesey, where he lived his whole life. It is written with great economy, repeating the first line three times, but such is its great character that congregations scarcely ever notice this.
