"Ysbeidiau Heulog" is the twelfth single by Super Furry Animals. It was released in a limited edition of 3,000 7" vinyls on the band's own Placid Casual label and did not break into the UK Singles Chart. In summer 2007, it was one of the tracks used in a series of adverts run by BBC Radio Cymru to illustrate the artists that first performed on the station in Welsh, before going on to greater fame later performing in English.
