This was on The Golf Channel last night and I watched a good portion of it and thought it was very well done. A pretty comprehensive look into golf and St Andrews history together. Tom Doak showed up in the second half and does a nice overview of the Old Course and a deeper dive into 4-5 individual holes that was very cool(assuming it was filmed during a Dunhill)-- would love to see the unedited full 18 if exists.
Looks like its available on-demand on Peacock if you have that.
