It must have been the Summer of '79 when I had a young teaching colleague from Yorkshire, who was forever trying to tell us in the staff room that Yorkshire were better than Essex. This was a bad time to be doing this, because 1979 was the first occasion that Essex won any trophies and they started with two: the Benson & Hedges Cup and the County Championship. They dominated County Cricket for the next 10 years or so.
They beat Surrey spectacularly in the final of the B & H and I was there. Sadly, the following day, in the John Player League, they had to play Yorkshire and every member of the Essex side gave the impression that they had the biggest hangover in the history of cricket. They lost ignominiously and this gave my colleague some valuable gloating material.
However, GB came to my rescue as he was opening or England against a pretty ordinary Indian attack in which they had no-one much faster than medium pace. Mr. Boycott kept on getting out to a bowler by the name of Ghavri, someone who, these days, Sir Geoffrey would describe as being "the sort of player that my old granny could score runs off".
My colleague was most miffed when I suggested that GB could also stand for "Ghavri's Bunny"
