Sounds like my kinda thing. Can you tell us the title/author?
Also: if you're into the history of Glasgow, I can thoroughly recommend the Hidden Glasgow forums. I've just recently discovered the site and it's taken over my life, it's so damn interesting!
They Belonged to Glasgow by Rudolph Kenna and Iain Sutherland. I really enjoyed it. Thanks for the website rec!
The P & J, heh. I know it well. Union Street is quite a bizarre piece of construction. It's hard to imagine Union Bridge looking like a normal bridge, without the shops.
I remember reading the P&J when I lived further north. Ever heard of the Raggie or the Inverness Courier?
