Doesn't that usually simply mean the reviewer forgot/chose not to put the date in? 
Yeah that sounds about right
No mention of a hairy bush, but then that would have been the norm back then so wouldn’t be mentioned anyway.
Topping up the tan (spray or otherwise) kinda gives it away. More likely to get sun burnt, wind burnt or go rusty back in the 70s.
Getting nostalgic now: Tan lines, natural boobs and a hairy minge still prevailed into the 80s all for half a lager and lime and a bag o chips = happy days.
