Two ace videos from YouTube of the great Django Reinhardt and L'Ot Cloob de France
Stephane had told me that the Macaferri had a very high and loose action, and if you look closely as Django picks you see that there's hardly any tension there. How on earth he made those fast runs. Oh, and you can also see clearly the damaged tendons of the fretting hand. Fascinating bit of musical history.
(PS - Props to the hot, clubbing Wells for alerting me to the original funky link. I sometimes suspect that Thou Tube doesn't really like one re-posting)
