Shadows Of Salford

Anyone know if this is just a reference to the town or, might it have something to do w/this passage from Peter Pan in Kensington Gardens?

"We are on the way home now, though of course, it is all pretence that we can go to so many of the places in one day. I should have had to be carrying David long ago, and resting on every seat like old Mr. Salford. That was what we called him, because he always talked to us of a lovely place called Salford where he had been born. He was a crab-apple of an old gentleman who wandered all day in the Gardens from seat to seat trying to fall in with somebody who was acquainted with the town of Salford, and when we had known him for a year or more we actually did meet another aged solitary who had once spent Saturday to Monday in Salford. He was meek and timid, and carried his address inside his hat, and whatever part of London he was in search of he always went to Westminster Abbey first as a starting-point. Him we carried in triumph to our other friend, with the story of that Saturday to Monday, and never shall I forget the gloating joy with which Mr. Salford leapt at him. They have been cronies ever since, and I noticed that Mr. Salford, who naturally does most of the talking, keeps tight grip of the other old man's coat."

This song, is so nice it makes me sad lol, I see as if it's about a love that one has some disability and the other one does not give up hope as the love between them is strong apparently.
