Intrigued, I stuck with Ms Knapp's 'artistic' muddle preserving my hopes til the song began. Not rewarded. Maybe she stopped flattening out the riches of the original tune eventually, but life is too short for me to have stopped around there to find out.
And here was me so pleased to find a younger person actually essaying a traditional song rather than their own acoustic composition with light trad flavouring.
Oh well, back to the songs in my head.
