Antony wants to speak at Caesar's funeral. What is Brutus's reaction? Cassius?

When Antony asks if he may have permission to take the body to the marketplace and show it to the crowds. Brutus gives him permission to do this, but Cassius warns, "You know not what you do. Do not consent / That Antony speak in his funeral. / Know you how much the people may be moved / By that which he will utter?" (3.1.234-237). As a compromise, Brutus decides to give his speech first, and to allow Antony to speak afterwards, provided that Antony only says positive things about the conspirators. Antony agrees.
