On Radio 4, I think, coming up for 3 years ago.
I was on my way to spend time with my friend in a hospice, this programme came on and carried me through the awful journey.
The programme was about the orchestral element of the record, how it had been put together, the work of a lady called Ann ( I think) and it was just wonderful.
I have tried searching for the info loads of times but never found it. I’d love to listen to it again and to share it with other people.
