Regarding the correct pronunciation, especially of the name Ralph: according to a friend at the BBC, the possibilities of this name - either aristocratic 'Rafe' or vulgar, almost Australasian 'Ralff' - lie in its potential for wilful mispronunciation against type. I saw him cast confusion into an over-confident studio guest by introducing him as 'Sir Rafe Halpern'. This was nothing to the consternation, almost disintegration of the personality, of the artistic, aloof actor brought on as 'Rolf Fiennes' ('Fiennes', naturally, pronounced superbly).
Hang a Ralph up at the next stoplight.
