Literally bumped into Ronnie at Cheltenham races maybe 6/7 years ago, windchill of minus God-knows what and he was heading back to his box (directly above the royal box and a better view I should think) as I was going up into the stand. I was too keen to get a decent view for the Champion Chase to try to hold him up - as he was too no doubt.
Other than that I can only think of assorted horseracing names, which I don't think is what counts on here
. So I'll just bask in the reflected glory of occasionally posting on this message board with all you famous people
