Gold Usher - you're right, this is a fascinating programme and I do recommend it.
I happened to hear it live and hoped it would be on the BBC i-player so that I could recommend it to everybody. However, when I looked online immediately after the programme, it said it wouldn't be on the i-player because of rights problems which is often the case with programmes about music. However, I'm delighted to see that they've obviously resolved those issues, and it is now on the i-player. As I'm Forum Moderator, I will break the rules this once and give you the link:
I really do recommend it - it's great listening!
PS IMPORTANT - I had to put a page return in the middle of the web address, as it seemed to disappear off the edge of the page. So when you copy the address, you will have to delete the page return to make it work.
