Calon Lan - Arfon Wyn - Côr y Penrhyn, Llanberis.

Diwrnod i'w gofio can mlynedd a hanner ers y Cloi Allan - Gyda Chor y Penrhyn, Hogia'r Bonc ac Arfon Wyn. Bu cyfarfod hefyd i drafod y newid dadleuol o enwau Cymraeg lleol i enwau Saesneg.
A day to remember one hundred and fifty years since the Lock Out - With Côr y Penrhyn, Hogia'r Bonc and Arfon Wyn. There was also a meeting to discuss the controversial changing of local Welsh names to English names.
