For the past 17 years I've specialised in music performance but more specifically lecturing on the social & historical development of music. I don't want to sound my own trumpet, but when it comes to this particular subject I can more than hold my own & similar projects always seem to tread the same ground. However, even I have learned some new info & seen & heard things that I hadn't before watching this. Upon reflection, I think it's greatest achievement was how it didn't keep cutting to a talking heads scenario, where the contributors talk about their reflections, as it solely used voice overs whilst still using the original footage of the time. It's an absolutely phenomenal piece of documentation & feel so glad that David Hepworth has been recognised as being the instigator of the project, who I've followed & listen to weekly in his podcast.
