I wish I had the actual PPs of his three (possibly even 4) killer races from 1964 to post. I have results with the times - and some cuts of form for some of the horses he beat.
Olden Times was 2nd by 12 and Kelso 5th by 14 to Gun Bow in a loaded '64 Brooklyn. Amazing because those are the kind of horses that are impossible to dust. Read the kind of stuff that was being said about Olden Times that summer.
And of course Kelso "the horse of gold" - was a 5 time Horse of the Year and one of the most beastly dirt route specialists ever.
* Here's a cut from '63 of Mongo - he's in the Champions book if you want his full PP's ...
After destroying Olden Times and Kelso in the Brooklyn - Gun Bow (under 130lbs) torched Mongo by 10 lengths in the Whitney - an excellent champion, Mongo brought career best form into that race and finished a distant 2nd.
