Tros y dwr i draeth Llansteffan - Over the sea to Llansteffan - is the title of this old Welsh tune. To harpists who came to the summer schools organised by Ysgol y Delyn at Ferryside in the 1970s, Llansteffan really was the romantic village just across the water, the sandy estuary of the river Tywi, site of an ancient river crossing on the route to Pembroke and Ireland.

In the BBC television film 'Their Harps of Gold', the five harpists who gave the first performance of this arrangement - Caryl Thomas,Valerie Aldrich-Smith, Siwan Jones, Shan Llewellyn-Jones and Adrienne Cowen - can be heard and seen playing it on the beach at Ferryside, with the sun shining on the river Tywi, the fishermen plying their nets, and Llansteffan and its castle in the background.
