John ac Alun is a Welsh country music duo formed in Tudweiliog in 1990. They are sometimes accompanied by Tudur Morgan (bass guitar), plus Charli Britton and Simon Barton (drummers). The duo has released eight albums in Welsh and one in English. They released their first album Yr Wylan Wen/Chwarelwr (The Seagull/Quarryman) in 1991, and received a gold disc by their label Sain in 1992 after selling 12,000 copies.

Both John Jones and Alun Roberts come from the village of Tudweiliog and they went to school together.[2] Jones is a former blacksmith and JCB driver, whilst Roberts works for Cyngor Gwynedd.

Most of their songs are written by themselves, but some have been written by Welsh poets and novelists such as the late Eirug Wyn.

In 1999, they went to Nashville, Tennessee, USA, where they sang and recorded at Sun Studio in Memphis.

As well as hosting a radio show on Radio Cymru, the pair has starred in four series of their own television show, John ac Alun, for the Welsh-language channel S4C.

Their 2016 album, Hir a Hwyr (Long and Late), was released on the Aran Label. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
