Thinking back to the mid-late 1960's and 1970's from what I can remember as a poor black child (ok, I'm white, but still was poor), was the way in which the speakers late in the day at Yankee Stadium (New York) on the week-long assembles could get the masses all pumped up.
The speaker would make a sentence in a very low, baritone voice. Always started with "Brothers". Then followed by a long pause.
Then, at a higher level, another statement.
Then yet, at a higher level, another statement.
Then, finally, almost yelling, "Brothers, don't we all agree that ........................................."
Everyone would clap, stand up, clap some more, etc, etc, etc.
The speaker could have said virtually anything (Brothers, don't we agree that the moon is made of cheese ... that there are aliens here among us .....) yes, anything. It made no difference what the speaker said, but everyone would still stand up and applaud.
It was kind of weird actually. You were standing up, applauding before he even finished the sentence and not even knowing what you were applauding for.
