I wasn't at Halifax but I was actually on a bus back from Maine Road into town when the draw was made, in the days when the draw was still made on Saturday (seems strange that, now!)
That day we had just beaten Derby 3:0 and someone had a 'transistor radio' ,as they were called in those days. When the draw was made everyone started cheering, little did we all know what lay ahead!
We got to the final the following year ofcourse (winning at another 4th Division Peterborough along the way) but In years to come whenever we were drawn against a lower division team away the reaction was often groans rather than cheers.
Barnsley, Brentford(when they were in 3rd Division) Cardiff, Chesterfield, Doncaster, Wigan....the list goes on!
