Even the seller does’nt know what’s on them or whether they work ok.I would think a good risk for someone willing to try but not too worried it is’nt as it seems..
I wonder if the BBC or ITV still keep any of the copies of interviews,do they ever replay Baders interview with Parkinson?.
Just googled,Radio 4 have alot but not Bader. http://www.bbc.co.uk/bbcfour/audiointerviews/
