Founded in 1974, one of the most popular pop and folk groups in Wales, and played intermittently for around 40 years.
Humour was a prominent feature in their singing from the beginning and they had a combination of folk singing - which was popular among the Welsh students at the time - and easy going original songs. There was a strong element of banter in the name itself (Mynediad am Ddim = "Free Entry") - an attempt to confuse publishers and readers of concert and 'nosweithiau llawen' posters.
