I remember the displays for Diary of a madman and welcome to the pleasure dome. Also went there for several concert tickets inc Queen at Knebworth
Walked straight into one of those floor-to-ceiling panes at that store when exiting much to the amusement of the people sitting outside.
Would have been '79 or '80 as I'd just bought a Gary Numan single
I remember all the punks would hang about out side spitting on the floor
I always felt intimidated at the thought of going in there, so usually went in Our Price or Woolies instead!
