Two games from my youth:
New Years' Day 1955. Blades 6, Newcastle United 2. A crowd of over 32,000 saw the Blades go four goals up in the first 8 minutes. Those arriving a few minutes late - from the pub perhaps - couldn't believe the score. I think Newcastle's keeper was an international, though I can't recall his name. The score suggests that the Geordies were a bit hung-over from a New Year's Eve celebration. For the record, the scorers were: Ringstead, Hagan 2, Hawksworth, Spencer 2.
The other match was, of course, Blades 7, Owls 3. 8 September 1951. Wednesday scored first but the Blades pulled it back to 2-1 by half time before going berserk in the second half. Scorers: Hawksworth 2, Brook 2, Ringstead 2, F.A.Smith. Hagan didn't get among the goals but I'm sure he must have had a few 'assists'. The crowd was 51,075.
Happy days!
