I had the extreme pleasure of being judged by him once in a comp. (To the elite-level Amateurs and to the Pros, this might not be such a big deal, but as someone who mostly dances Pro/Am it was a big deal.) It was the 2002 USDSC, and I was having a horrible time at the comp. The first day I danced was the single-dances and I was last in all my events. He was not on the panel that day.
The next day was the Scholarship, and I was just so "over" the comp at that point...but when I looked at the marks afterwards, not only was I not place last, I had also earned a recall from Mr. Irvine in the Foxtrot. That was pretty special to me, and made my day.
If you ever get a chance to read his autobiography, "The Dancing Years," do so. It's got a lot of great pictures of him & Bobbie back in the day in it, too.
