Can't think of any specific traditonal songs. Hergest did a song back in the mid '70s. Guto Pryderi Puw has done a modern classical piece. The story has been told in all kinds of dramatic forms in Wales, from the ultra-classical to pantomime.

On a bit of a tangent, birds in Welsh folk songs have changed over the decades/centuries. The blackbird is in many songs sung today, but in the past the 'fashion' has flipped and flopped; owls, magpies, seabirds, etc. Siwsi George was working on an album of bird-related songs when she passed away and the project was never finished ... more's the pity.
