Mr. Pettifer, It's wonderful to find you on here on RU-vid. The "Diamonds in the Sky" series was exquisite journalism. I first watched the series in 1986, on The Discovery Channel. I recorded the episodes on VHS and still watch them to this day! I wanted to thank you for your work and send you my best regards.
It may be a bit late to ask but what was the programme you made of the natural world, around 1990/91/92? I recall the wolf you sat with as it was sniffing your hair. Would love to see that series again.
