BOAB.... do you, or any here , remember the Billy Connoly parody of 'HELP ME MAKE IT THROUGH THE NIGHT'

I am certain on of the lines included a reference to CHANTY... but it was obviously a Glaswiegian object... I have no idea what it is but he sings:

" take the curlers from your hair
shake em loose and let them fall
lay them down by your glass eye
by the CHANTY on the wall,
thou your teeth are black and gone
and your breath smells outasite
I'll put a claespeg (clothes peg) on my nose
to help me make it through the night "

SUCH a cheeky boy... !! but what is the chanty he sings of?
