Mhairu

Like the evening sun sinking to the water
The day gives way to dusk and dusk to night
Like a circle turning round
Like a season turning brown, I'm home again

Mhairu, it's good to see your friendly face
When I don't see much left of what we knew
In my need to see a light
I saw it shining bright when I saw you

Oh they burn my castles down
Oh they burn them to the ground
They burn them to the ground

Mhairu, I don't say we don't need changes
But I question "Is it changing for the good?"
When I look around this town
And I see strangers take the place of friends we knew

Oh they burn my castles down
Oh they burn them to the ground
They burn them to the ground

They burn my castles down
They burn them to the ground
They burn them to the ground
