I will throw in my pennies worth.
In talking with the 'old timers' here I got the impression that Elliot was an amazing talent with a mind of steel and that Percy learned how to 'get to him' to extract the best from him. Is that true ?
An aside : I have mentioned this before but I recall a conversation with Neville Scott many years ago when we asked Neville who was the hadest or best he raced. Snell or Elliot.
He said Peter would just 'explode' away from you and have 20 metres before you knew it.
Herb, he said, would 'grind you into the ground' just taking a metre at a time and that he would leave you with the feeling you could do nothing about it.
I was only 11 years old but I still reckon that 1500 in Rome in 1960 was one of the 'greats' in terms of Olympic 1500's.
Also a great Olympics for Australia and New Zealand with 3 golds and 2 bronze medals.
