Mam recalled going to a Lyon's shop somewhere on Long Row, maybe just after the war. I popped into the Archives to look it up for her and found it in Kelly's dated 1936. I transcribed the whole of Long Row so thought I'd post it here in case anyone else has an interest.
By the way, the Archives are closing at 1245pm on 18 October for some building works and re-opening next Spring.
Anyways, here's what Long Row was like back then:
