Joe, I have Joe Corrie's booklet, "Scottish Pride and Other Poems".
Slight corrections in The Image O' God.

Verse one, last line:Jings! but it's laughable, tae.
Verse two,first line: Howkin' awa' 'neath a mountain o' stane,
Verse 4, last line: Jings! but it's laughable, tae.

Small corrections but I'm looking at his booklet.

I cannot comment on the "pit heid" but "bait" usually meant one's "lunch".
