[2] With St James' Park open on only three sides, due to the ongoing construction of the East Stand, the match kicked off and Hereford took a shock lead after 17 seconds.
Brian Owen ran around the Newcastle defence onto the end of the free kick, and put the ball past Willie McFaul to give Hereford a dream start.
At the time, it was written that Malcolm Macdonald had said ahead of the match he would score ten goals against Hereford in the replay, to beat Ted MacDougall's record.
Newcastle had been forced to travel down to Herefordshire on three separate occasions, in the end staying for much longer than anticipated in a hotel in Worcester to get the match played.
Almost immediately Newcastle were on the attack as Macdonald latched onto a misdirected header from Ronnie Radford and broke into the Hereford penalty area.
Hereford's Dudley Tyler had a couple of shots in the early stages which McFaul was equal to, before Addison was booked for a late challenge on Irving Nattrass, a foul the Newcastle centre half did not appreciate.
From the resulting free kick on the Newcastle left, Potter made a brave save with Pat Howard poised to score.
He was to make up for this miss soon after when Viv Busby, on the Newcastle right, supplied a deep cross which Macdonald headed in at the far post to finally break the deadlock.
George's fresh legs were to pay dividends minutes later when he won possession on the Hereford left, turned well and found Mallender.
The return pass bobbled on the muddy surface but sat up kindly for Radford who unleashed a strike from 30 yards (27 m) out that, in the words of commentator Motson, "flew into the top corner of McFaul's net".
The footage of Ronnie Radford's wonder goal has been replayed endlessly and the images of him celebrating with arms aloft, and the crowd invading the muddy pitch have become immortalised in FA Cup history.
The replay at Upton Park was played on 14 February, a Monday afternoon, because of power strikes, related to the Three-Day Week, in front of 42,271 spectators with a further 10,000[citation needed] locked outside.
It was initially named after Radford, who presented the award to representatives of the winning team during the half-time interval of the FA Cup Final.
