He's actually done heaps of decent things for various individuals as well as charities and at 76 years of ages still seems to be tireless in his efforts.
I know inevitably someone is going to come on say something horrible and I'd like to suggest that says more about them than it does about Monty.
When Monty first came to the UK he was invited by Her Maj to demonstrate join up methods on her horses, she has quite a few if we include the Household Cavalry and all the TBs, Fell ponies, Highlands and so on.
I imagine she has kept in touch as they say, and he has probably been nominated by others for work with equine charities and Racehorses etc.
