Hiya Chris & Fee,
Great radio show - you are doing a wonderful job of playing stuff that no-one on the BBC is bothering with, for reasons quite unaccountable to many of us.
Of course I am up for a session of Welsh songs - PM me about it.
You ask for suggestions of Welsh songs/ recordings available. You could try playing some of Siwsann George(Traditional Songs of Wales ; Saydisc CD-SDL 406 ) - or Mabsant of which Siwsann George was a member. There is Calennig - the wonderful Mick Tems & Pat Carron-Smith or the hauntingly beautiful voice of Sian James. 'Gweini Tymor' is a favourite album of mine , on Sain SCD 2145.
There is the triple harp playing of Robin Huw Bowen or Nansi Richards or Llio Rhydderch.
You could play some tracks from the duo Bragod, they get a fair amount of interest from Late Junction on Radio 3.Wierd but wonderful stuff it is too.
Try that for starters! And don't stint on the Julie Murphy!
Mary
