For this is the day when Bobby Charlton, Denis Law and George Best were selected in the same United starting XI for the first time.
Manager Matt Busby decided to unleash the legendary trio in a Division One match against West Bromwich Albion at The Hawthorns and, given what followed, it turned out to be a pretty solid decision, all things considered.
Best had made his United debut in the corresponding home fixture versus the Baggies four months earlier, a match Law missed.
With a view to easing his young charge into life as a senior footballer, Busby had returned the 17-year-old Belfast boy to the second string for three months after his initial breakthrough.
