Like many other current affairs shows in the 70s, Tonight had a fairly brief existence, but it provided the forum for this infamous battle of wills between journalist Simon Walker and Prime Minister Robert Muldoon.

Muldoon grows increasingly annoyed and bullish at being asked questions that are not on his sheet: "I will not have some smart alec interviewer changing the rules half way through."
