Those were fairly typical attendances for the most part at the time, they'd be much higher now. Chelsea's visit to Man City for example only attracted 200 more people than Notts. Less people were at Main Road to watch their league clashes with QPR, Coventry, Luton and Wimbledon.
Our visit to Fword was their biggest crowd for a number of years and I'm not even sure it's been bettered since.
