I have found the Song-O-Matic very useful ever since RT finally opened his own Official website. There are various Thompson songs which people sing incorrect versions for, because - I presume - somebody has transcribed them incorrectly, and others have learned them from this intermediate source. (Okay - I know I've altered a couple of words when I sing Hard Luck Stories, but we do, to fit our own style of delivery, don't we).
There are TWO versions of Dimming of the Day in the Digitrad, DIMMING OF THE DAY and THE DINNING OF THE DAY (2) . Both these have the verses jumbled, and the words differ from RT's official words.
It would be worth cross-checking Digitrad versions of RT's stuff against this own web site.
Quack!
Geoff.
