The "old thread" linked above has gone 404. Here are the lyrics, copied from a YouTube video.

Long have I wandered far and wide with my harp in the misty mornings
Many's the song and the tune I played on many a starry evening.
Played you a jig and I played you a reel
Played for a penny, a drink or a meal
But I dream of a day at court I'll kneel
And play to a king and his lady.

Well I've waited long to play my songs
But now I am old and leaning.
You hear the old man sighing near
'Tis Finagle the harper dreaming.

In the summers I played in the meadows green
with my songs both gentle and stirring
In the long cold nights I played in the light
of the tavern fires burning.
Songs of the forest and songs of the sea
A song for your brother and a song for thee
But I dream of a day at court I'll kneel
And play to a king and his lady.

But the seasons they pass and the short years fly,
creeping upon my shoulders
The legs grow weak and the eyes grow dim
and the nights are feeling colder
Now I am aged, my head is old
My hands are feeble and my fingers cold
And my songs are forgotten and strewn by the road
All of my tunes are forsaken.

That'll cheer everybody up.
