Someone the other day mentioned this thread to me so I've quite enjoyed watching it unfold. I wrote the song way back in 1986, so 'not a lot' is the short answer to Bruce From Bathurst's question.

I do still occasionally dust the song off, as it gets requested now and again, and yes, it's in my website songbook so I guess the awkward rhyme doesn't bother me over much. I probably wouldn't have used it if I was writing it now but I'm fairly relaxed about stuff like that from the dim and distant.

Two lines were in my mind at the time, I recall. 'I've done my share of humpin' wi' the dockers on the Clyde' (Trad Scots song Tramps and Hawkers) and 'When he gets a few jars he goes frantic, He's tall and he's dark and romantic and I love him in spite of it all' (Lassies From Kimmage by Luke Kelly). I seemed fine at the time and no-one's bothered much till now, so I got away with it for over twenty years I suppose! Anyway, it's nice to know folk care enough to post.
Best wishes to all,
Alistair
