Nit picking,I know;but the McPhee has been or was available as a cd. I downloaded it a while back from Amazon. It's very probably a different performance,anyway.
But virtually everything else is unattainable. As far as I know.
You're British catalogue is in the mind boggling category.
Ony two disappointments. No David Wynne or the complete Radio 3 performance of Holst's opera 'The Perfect Fool'. Oh,and Daniel Jones's Fifth!
But with treasure trove like that,picking out very minor omissions like that,IS nit picking!
(I should be ashamed of myself!) Let's all just hope to goodness that the tapes are okay!
You're attic finds,Dundonnell, remind me of a cartoon in Private eye,which showed a bloke on the Antiques roadshow,with a water cistern on the table,saying " I found this tucked away in my attic. Do you think it's worth anything?"
Thankfully,you've done allot better than that!
