"Return with me now to the thrilling days of yesteryear” is how the old Lone Ranger radio shows began.
The Inquiring Iguana couldn't help thinking of that phrase when he stumbled across an eight-minute travelogue about St. John, produced in the ‘60s by Midwest Film Studios and available online.
About three-quarters of the film focuses on the development of Caneel Bay, new at the time. There are shots of the sand and the surf, of course. The deep-voiced narrator explains, The “slave quarters (have been) remodeled as pastel-tinted cottages …the old Sugar Mill is now a shop.”
There was a golf course pictured (which Capt. Doug, in a comment, said is on St. Croix).
The film is available at the Travel Film Archive, which appears to be a real trove of treasure for travel veterans. Here's a link.
