Aerial views of the glorious Pembrokeshire coast and countryside, with St David's cathedral and Tenby, to illustrate some features of The Wayfarers Walking Vacations' walking holiday through Pembrokeshire in Wales. The accompanying music is a tremendously rousing version of Cwn Rhondda (Guide Me, O Thou Great Redeemer) performed by Liverpool Cathedral Brass Ensemble, Liverpool Cathedral Choir, Massed Choirs from Merseyside, Ian Tracey & Ian Wells. They really - to use an idiomatic phrase - give it some welly.
