If you've not seen this you may enjoy it. Quaint old episode of Chronicle with Alexander Thom (and his curious Hitler 'tash) from 1970.

Accurate or not to modern eyes and ears, I love these old programmes, they're part of what fired me up about the mystery of prehistory as a kid. Plus it's nice to see sites as they were 30 or 40 years ago, when peeps were less interested in our prehistory.
