Looking for the tune to the Gaelic song:
Oran Air Breith a Prionnsa Tearlach by John McLachlan

The first verse reads thus:
'N naigheachd a fhuair sinn an drasd'
A thainig oirnn nuadh do'n tir
Chuir m'airtneal air chairtealan uam
Dh'fhag aigeantach, uallach mi
Cha bhi sinn tuilleadh na's mo
Aig Deorsa fada fo chis
Thig sonas ri linn a' Phrionns'oig
'S gheibh fir tha air fogradh sith.

meaning:
The tidings we have now received
Which are freshly come to the land
Have chased all my sorrow away
And left me both joyful and proud
No more are we going to be
Under subjection to George
Joy will come in the young Prince's time
Peace will be to the exiles restored
