Thanks for the reply BJ and I agree there must be a list somewhere.

In my case I saw a race, remembered the horse run and its colors but without sound etc it was hard to determine horse name. I bought the paper next day and going on the placings I have narrowed the horse to one of 5 names!

Anyway I've since learned that if you have bigpond broadband you can get video replays. Problem will be solved and nag's name known after I visit my brothers place.
