Sosban Fach is a traditional Welsh folk song. It is one of the best-known and most often sung songs in the Welsh language.

The song is based on a verse written by Mynyddog in 1873 as part of his song Rheolau yr Aelwyd ("Rules of the home") — see below. Talog Williams, an accountant from Dowlais, created the song we have today by altering Mynyddog's verse and adding four new verses.

Sung by Heather Jones, accompanied by Chris Jones on guitar, as part of the Alawon Fy Ngwlad joint project between trac, Caerphilly County Borough Council and Menter Caerffili. You can read more about the project here https://soundcloud.com/traccymru/sets/prosiect-alawon-fy-ngwlad-tunes-f…
