Mick - Thanks for the pointers. After a year or more of searching, I now have a tune which is probably "When Phoebus did rest". I'd missed it before, because the ABC of both tunes have the title 'Drive the Cold Winter Away'.

The first tune (125) sounds a little odd to me. It's marked as DDorian, and in the second half there's a mixture of C# and C which grates on my ear. Does anyone else agree? Could it be an error in transcription, or is it just me?

Phil
