Edwin P Lees was a favourite of mine, they used to sell records downstairs before moving to the upper floor for more space. I bought lots of Punk, post punk, Gary Numan stuff in there. Awesome staff too. I remember Crass and the Anti Nowhere League records causing them a few problems with the obscene publications squad coming in to stop them selling them at the time lol.
In the book 'Young Soul Rebles' Stuart Cosgrove mentions the Molly brothers who brought their first soul record there amongst the light bulbs, lamps and extension cables. Upstairs was a rack of chart records and small box of imports. Dave Molly's love of digging began along with Richard Stearling drove mile's in search for northern soul.
