There’s a Flaw in My Flue lyrics

I used to sit by my fireplace
And dream about you
But now that won't do
There's a flaw in my flue

Your lovely face in my fireplace
Was all that I saw
But now it won't draw
'Cause now my flue has a flaw

From every beautiful ember
Her memory arose
Now I try to remember
And smoke gets in my nose

It's not as sweet by the unit-heat
To dream about you
So darling, adieu
There's a flaw in my flue
