Classic Children's Book 'story tape' - The Old Man of Lochnagar by Then H.R.H. The Prince of Wales

This was my favourite 'story tape' when I was a boy. I had searched the internet long and hard, but could not find it. I have long ago lost the original tape I remembered so fondly. Finally, a kindly seller on ebay sent the record, which my dear Mum arranged for my 50th Birthday and my nostalgic journey is complete. I wanted to put this out to the world in case anyone else looks for it and would like to hear it.
