Another version:
Oh the summer time is coming
And the trees are sweetly blooming
And the wild mountain thyme
Grows all around the blooming heather
Will ye go, laddie, go?
I will build my love a bower
By yon crystal flowing fountain
And in it I'll put all
The flowers of the mountain
Will ye go, laddie go?
If my true love he won't go
I will surely find another
To pull wild mountain thyme
from all around the blooming heather
Will ye go, laddie go?
And we'll all go together
To pull wild mountain thyme
From all around the blooming heather
Will ye go, laddie, go?
