Fox's in Doncaster was my record shop of choice as a teenager in the early 80s. The first singles I bought were 'Holiday 80' by the Human League and 'Messages' by Orchestral Manoeuvres in the Dark on 10". Fox's also had musical instrument shops in Doncaster (across the Arndale from their record shop) and Sheffield (which also had a small record section). I believe they also had a store in Hull.
Chas. J. Fox (Piano) Co. Ltd or simply Fox's as it was known locally also had a record shop (separate musical instrument shop next door) in the Galleries at Washington, Tyne & Wear, from the late 70s until sadly closing in the middle of 1982. I worked there for the last year of it operating with the best group of people I ever worked with. Phred, Big Chris, Little Chris and Donna. Best job I ever had, even if crap money lol and I'd go back to those days in a heartbeat!
