A Celtic Dream

Ciarán Brennan / Daniel Brennan / Lynda Brennan / Moya Brennan / Paul Brennan

Beneath the mountains in the mist
A shining light rising North-West
Where ancient kings ruled the land
Heroes lost and won

Voices echo through the glen
Where secrets come alive
Into the wild wood and sacred groves
In a Celtic dream

That was such a long time ago
We didn't have a care in the world
Imaginations running wild
It was just a Celtic dream

Rocking stones from long ago
Form a lasting sight
A shooting star on a magical night
It was a Celtic dream

That was such a long time ago
We didn't have a care in the world
Imaginations running wild
It was just a Celtic dream
It was just a Celtic dream

Down the path of a hallowed place
Where music comes alive
With pipes and drums all the dancing is done
By a candle light

That was such a long time ago
We didn't have a care in the world
Imaginations running wild
It was just a Celtic dream
It was just a Celtic dream
