Three of my favourites are A Constable Calls, Follower and Mid Term break. Also

The Given Note

On the most westerly Blasket
In a dry-stone hut
He got this air out of the night.
Strange noises were heard
By others who followed, bits of a tune
Coming in on loud weather
Though nothing like melody.
He blamed their fingers and ear
As unpractised, their fiddling easy
For he had gone alone into the island
And brought back the whole thing.
The house throbbed like his full violin.
So whether he calls it spirit music
Or not, I don't care. He took it
Out of wind off mid-Atlantic.
Still he maintains, from nowhere.
It comes off the bow gravely,
Rephrases itself into the air.
