Thanks Freddy
I think you are right about the 'wide' mills and 'industry's changed'. Thanks for taking the trouble to listen and report these corrections. When transcribing a song it is very easy to get an idea of what you think it is (or what you think it should be) into your head and then you can't see the (correct) alternative. Fresh ears have certainly helped in this case.

With regard to the 'boat names' Steve, I'll make further investigations along the line you suggest. I originally thought that these might be names of mills - as they 'still remain' and boats are unlikely to have done so, unless they are preserved by some organisation or loving owner. A preliminary search for mills in Manchester with these names was fruitless. The search continues - thanks all.
