Just done a quick recheck - there are fifty alphabetic characters in the phrase, and when I checked before, they all corresponded with the Tom Wait quote.

(All those letters writing all those letters to all those other letters! just think!)

EDIT and what a marvellous clue. Same letters, in different order, saying (more or less) the same as the original phrase - I really admire people who can make anagrams which refer to the actual answer, as this one does.
