So the question remains; why sit through a conference speech if you already know the content?
Three reasons: love of a particular politician; to get a sense of the dynamism of the individual speaking; and to see how on-side the audience is – how willingly, at what volume and for what length of time will they applaud.
Boris Johnson's speech certainly fell into the first category. Those present were treated to a well crafted speech, liberally scattered with 'bons mots' and trademark bluntness, and they were in the mood to be delighted.
Grins and applause followed his remarking on "the baggage handlers [of Ed Miliband's] memory [going] on strike", his faux-modest acknowledgement of being just a "municipal toenail" and a "parliamentary candidate", through to giving his audience "permission to purr" over the referendum result, and summing up a "new a Fisheries policy... first chuck Salmond overboard and then eat the kippers", before finally a prolonged ovation as he called them "to the barricades".
There was, however, another star with a keynote speech, one of David Cameron's so-called "team of leaders" – Theresa May (George Osborne and Johnson being the others).
Delegates were treated to an opportunity to compare and contrast both contenders, with their speeches following in quick succession.
In contrast with Johnson the subject matter was heavy – police discrimination relating to stop and search and the terrorist threat.
It was a statesmanlike speech of a very different style, where applause seemed to be more disruptive than welcome.
The standing and wholehearted ovation at the end, however, proved the value of staying true to her own style.
The consensus appears to be that May won the day in terms of any future leadership bid.
