With thanks...

... to Melvyn Bragg for starting to say that [some 17th century farming activity] represented a "quantum leap", then stopping at about the "l" of "leap" and saying "I'm not going to use that term", and altering it to "a great leap forward".

Much respect.

NZS love you, Mr Bragg.  Even if you didn't give us a podcast last week.
