I have great memories of the John Player, at one point in the history of the competition there had only been 3 ties and I saw 2 of them.
The most memorable of those was against Somerset, needing 2 to win David Shephard out to the boundary right in front of where we were sitting. A young Viv Richards (maybe his 1st season?), dropped the catch on the boundary, but was quick witted enough to immediately pick the ball up and throw it straight over the stumps and run Shep out before he completed the 2nd run. Amazing presence of mind which made everyone sit up and take notice of him.
My first memory was less exciting, my dad took me to see Gary Sobers play for Nottinghamshire, but thanks to some passing thunderstorms all I saw of him was being interviewed under an umbrella by Peter West. I often wondered if we would have been there at all if dad had known it was going to be televised.
