Virtually every song written by Dave Goulder. The January Man is the best known but to my mind there are many that are better. I'll just mention the first four that come to mind -
"A Boy In Winter"
"Sandwood Down To Kyle"
"The Long and Lonely Winter"
"A Most Unpleasant Way"
"Far Away Tom"
"The Carpenter and the Sexton".
Yes, I know, byt there wasn't one that could be left out.
Then there are all the brilliant songs by Leon Rosselsom and Pete Morton.
