In 1958–59, Crook beat Ferryhill Athletic in the first round of the Amateur Cup despite losing Snowball mid-match to a broken nose.
[15] They progressed to the final in which they beat Barnet 3–2, a victory masterminded by Seamus O'Connell, twice an Amateur Cup winner with Bishop Auckland, despite his having been in a car crash on the way to the match.
[19] Crook won the Amateur Cup again in 1962, beating Hounslow in a one-sided replay at Ayresome Park, Middlesbrough,[20] after the Wembley final was drawn 1–1.
[23] That season they again won the Northern League,[18] and the following year reached the Amateur Cup yet again, despite an error-strewn performance by Snowball against Barnet in the semi-final.
[24] In the final, Enfield were ahead by a goal scored when Roger Day took advantage of Snowball and Peter Garbutt "each wait[ing] for the other to clear a back pass on the byline".
