Dreg Song as sung by Archie Fisher

DREG SONG

The herring loves the moonlight
The mackerel loves the wind
But the oyster loves the dredging-sang
For they come from a gentler kin
Jeery ory alley
Weel row'd five men
As weel as your ten
The oysters are a gentle thing
They would nae tak unless you sing
Come buy my oysters aff the bing
To serve the sheriff and the king
And the commons o' the land
And the commons' o' the sea
Hey how Harry-O
Many a boat skail'd the ferry
Many a bonny fishing boat
Tell me a true note
True note true sang
I've dreg'ed ower lang      
Ower lang ower late
Quo' the haddock tae the skate
Quo' the skate tae the eel
Cock nae I my tail weel
Pull weel tae the shore
Hey Harry rest your oar
Jeery ory alie
Weel row'd five men
As weel as your ten
The oysters are a gentle thing
They would nae tak unless you sing
Come buy my oysters aff the bing
To serve the sheriff and the king
And the commons o' the land
And the commons' o' the sea
