The song you mention reminds me of Dream Angus:
Can you no hush your weepin'?
All the wee lambs are sleepin';
Birdies are nestlin', nestlin' together--
Dream Angus is hurtlin' through the heather.
CH: Dreams tae sell, fine dreams tae sell.
Angus is here with dreams tae sell.
Hush now my bairnie, and sleep without fear;
Dream Angus will bring you a dream, my dear.
Sweet the lavrock sings at morn,
Heraldin' in a bright new morn.
Wee lambs they coorie doon together,
Alang with their ewies in the heather.
I heard that on an "Orealis" recording. (They are a band from Quebec that plays Scottish music.)
