I think the first time I read about this quote was in a book about Test Match Special
which I took out from a library near to my boarding school in Cheshire. I remember one of the first matches I watched on Sky after returning home for the summer holidays that year was when one of the commentators was Michael Holding and one of the umpires was Peter Willey. I therefore thought to myself "the commentator's Holding, the umpire's Willey"! However, that would involve longer arms and a longer Willey than if they were bowler and batsman respectively.
I am not sure whether there is any surviving recording of the quote being uttered. If there was
, then there wouldn't be such debate about who said it. The quote appears in a radio advert for DFS of all things
, but I think the voiceover may have been done at a more recent time. I can't really help much, as I am neither a regular listener to radio nor someone from the era in which the quote was uttered.
