Can't make it out either. Looks like cranes in the background. Looks like canals, not river, which would fit with Wigan but I don't think there are any cranes in that area.
goodoldphil - If you supplied the flower ladies, you might recognise someone in these pictures from 1983, taken in Williamson Square, and outside the Lyceumn. The locations are still there, but changed a lot and the flower sellers seem to have gone all together.
