I used to be a mad showjumping fan in the 80s (haven't really watched it much since, I converted to eventing in the 90s). I was searching around You Tube for videos, and amazingly enough found some 80s stuff. I thanked the guy for putting them up, and he said he'd loads of stuff on VHS from the 80s that he was converting to digital and posting on YT, so I asked if he happened to have Annette Lewis and Tutein
jumping at Hickstead? He had a look and asked "this one?"
Yup, that's the one, remember it soooo clearly (you need to watch it all the way to the end)
