Gwahoddiad from Gwawr by Estron
Gwahoddiad (Invitation) is the tune for the well known hymn `Mi Glywaf Dyner Lais', composed in the mid 19th century by the American revivalist preacher Lewis Hartshough and with words put to it by Ieuan Gwyllt. This is so well known that it's almost impossible to play it in Wales without someone bursting into song...
John Tose is well known on the Welsh traditional music scene as a maker of Welsh bagpipes and pibgyrn, and as a performer in such groups as Pibe Bach, Pibau Preseli, and currently, Estron.
