I can tell you a similar story of a seventy year old Col CK Nayudu facing upto India's fastest bowler of the early sixties, Rajinder Pal. Col Nyudu strpped into the nets with his necktie tucked in after taking off his immaculate jacket and after Rajinder Pal had sent him a couple from a short run up, chided him to bowl some aster stuff as befitting India's fast bowler.
Rajuinder Pal bowled from his full run up and the Colonel kept driving him in front off the wicket off either foot.
I was lucky to be watching as a wide eyed teenager and have never since questioned anything I heard about old timers as mere hype.
Colonol Nayudu died 2-3 years after that.
