When Liverpool reached the 1965 FA Cup final, a couple of days before the Wembley showpiece, Reds captain Ron Yeats received a phone call from Buckingham Palace.
The Queen would present the trophy to the winners of the game between Liverpool and Leeds United, and palace intermediaries had called, to brief both skippers on the protocol for the occasion.
They made it clear that should his side win the trophy, Yeats must not speak to the Queen until she had addressed him first. The towering defender was also told to respond, if appropriate, with only a “Yes Ma’am” and “No Ma’am.”
