It was the 70s - but the fields were outstanding and miles better than the Masters last year.
Off the top of my head in 1977 they had:
Nicklaus, Palmer, Crenshaw, Pate, Leitzke, January, Barber (Miller) McGee, Bean- and I am sure I have left a few out.
David Graham won - and of course there were the best Australians including Norman,Shearer and Devlin.
It was an amazing few years - and most of them came because of Nicklaus and a $6000 fee.
Putting together an equivalent fiield now would be more than $6 million. Jack is Tiger so that is 3m gone for a start and Arnold is Mickelson so that is 5m already!! There is at least another 2m for the rest.
