A somewhat "back-yardish" video of *Menai Mister Mostyn (Spencer) does exist and can be purchased if you are considering him as a stud. The video was made on a farm without any formal rings.  We did do a good job of showing his conformation. Since Spencer has only been shown in hand, there is no real canter on the video.  We did however include footage of him being chased around a field.   Check out those lead changes.
