It's strange how the memory plays tricks. I listened to the 'PM'item on 'Singing Together' and was amazed to hear William Appleby's strong Yorkshire accent.
It all makes sense of course, as I believe Mr Appleby was a Yorkshire schoolteacher.
But I could have sworn that he had a hearty upper-class BBC type accent. Obviously not.
As I say, the memory plays tricks and I could be confusing Mr A with any number of 'received pronunciation' types which the BBC used to broadcast into our little country classroom all those years ago.
