Back in the 70s we didn't have a lot of home grown surf films so any foreign ones available were mainly imported by Three S films of Penzance, and came from Oz and the US. Check out the ad, a surf video for £35 in 1981 !!
In the US films Pipeline invariably plays a big part and here's a couple of clips of it in the late 70s; one from Freeride, one of the best films of the era http://www.youtube.com/watch?v=E5rNvQtLGQo ; and here's an obscure clip from a film called Sevano's Seven in 1979 which features a great soundtrack and some accomodating ladies, http://www.youtube.com/watch?v=TLmjqtTa6MI ,the sort of film that inspired surf trips away from Britain in winter.
