I was listening to McCain 's nomination acceptance speech on the radio on the way to the airport yesterday and it sounded so different than it did in the arena . I actually got to hear the fiery end to the speech , the part where he said : Stand up , stand up , stand up and fight . Nothing is inevitable here .
Why did the speech sound so different ?
