Many further thanks, all - som great suggestions above;

I note that many of them are relatively recent, or else from the mid-70s to early 80s - can anyone recommend earlier ‘source singers’?

I’ve encountered Phil Tanner - who else should everyone hear?

Are there Welsh counterparts to the McPeakes, the Coppers or the Stewarts? What about a Welsh Jeannie Robertson, Margaret Barry or Phoebe Smith?
