If you mean audio rather than video, well there are a fair few Jo Ann Kelly albums available, the best being her first. Just look on amazon.

And there are absolutely loads of Duster Bennett CDs availalable too. Jo Ann and Duster are IMO the best british blues artists. Both passed away of course. But you'd have thought the BBC could at least have done what they do on so many of those documentaries when they don't have footage - a moving-camera photo montage with music/narration on top. Their recent Supremes tour doc did pretty much nothing else, they had so little footage.

They also didn't mention Duffy Power, Mike Cooper, Simon Prager or Ian Anderson of course. It would have been nice to have had Christine Perfect involved too.

Actually I heard Mike Cooper say that he was in fact contacted by the makers of the documentary, but their budget couldn't stretch to flying out to Rome to interview him, or to paying for him to fly to the UK.
