Calderwood concedes that the prospect of an FA Cup upset in the Sixfields Stadium on Sunday are remote, but I told him to tell his players that, in 1970, the late Dave Bowen's side were only two-down after 50 minutes - and they missed a penalty. That day a crowd of 21,711 paid record receipts of ?17,000 and did their best to create an intimidating atmosphere. I remember the police moving on to the terraces in force to subdue fighting fans.
