Now Green Gartside is from Wales. He went to Croesyceiliog Grammar School in Cwmbran ..... he might play some Welsh-language stuff ...after all, he's got 3 whole hours to fill.
And if he did play some,I'm sure it would be really interesting stuff, because that's the sort of person he is. Mind you, he's just made of molecules and things like we are.
A crafty way to find out without actually listening to the thing is to wait till it's over and then look on the "playlist" ... most ( all ?) of the BBC6 Music programmes publish a list of all the stuff they've played. I've found some good stuff myself that way, by looking at Mark Radcliffe's playlists for his Freak Zone and Freakier zone transmissions. Smart eh ?
So there you go ... you are better informed than you were a few minutes ago. But again, maybe you could have obtained some more valuable and useful information in the time you've spent getting this lot of information.
And now ... your very own .... your own ... Meic Stephens when very very young indeed and dressed in the sort of outfits people dressed in at those times .... with a remarkable performance of Roedd Gennyf i Gariad ... absolutely brilliant !
