• This week’s meanderings centre on public speaking. Trigger for this was the BBC Radio 4 replay of Enoch Powell’s 1968 infamous “rivers of blood” rant. It makes one appreciate that powerful speakers can be a force for bad as well as good. Churchill, JFK, King: inspirational. The great Shakespearean soliloquies – Henry V, Julius Caesar (I wonder if he ever gave those ears back)? Flip-side? Hitler, the aforementioned Powell, Mosley (with his pathetic moustache and girlie voice), disgraced American evangelists pleading with gullible fools to dig deep “as the Roller needs replaying”.
