Here's an out-of-print instructional video by the "Silver Scot," Tommy Armour, and somebody put a copy up on YouTube. The original film was made in 1954, and it's particularly interesting because it's designed to go with Armour's teaching guide How to Play Your Best Golf All the Time... and the book IS still available.
Why am I so pleased to find this? Because Armour originally made this film to explain things in the book, so they actually give you page numbers during the video.
I think Tommy Armour's book is still one of the best instructional books around, even though it came out in the 1950s. It's a simpler approach than Hogan and it's a good way to learn the basics of a golf swing similar to the greats like Sam Snead.
Have fun with this one!
