The trio marked the occasion, a 4-1 win over West Brom at the Hawthorns, by sharing the goals between them. Law scored twice, Best nabbed only the second goal of his fledgling career, and Charlton completed a good afternoon’s work.
Charlton and Law were firmly established in Matt Busby’s side by the time the United boss decided the moment had come to give the precocious Best a run in the first team, several months after his debut in the first meeting with West Brom earlier that season.
The Irishman and Law had lined up together a week earlier, but Charlton's return for the outing to the Midlands meant the world got its first glimpse of the Trinity. It clicked straight away, bagging 37 goals in 20 appearances together by the end of 1963/64, before tormenting defences all over Europe for years to come.
Former team-mate Paddy Crerand had one of the best seats in the house when the Trinity were in their prime.
"George was just George: a total one-off," he says. "Denis was brave as anything and a fantastic player, and if somebody could tell me which was Bobby’s best foot – left or right – they’d be educating me. I could never tell."
