Today's guest left a tweet in anticipation of the occasion --

Here's the event itself. (For the record, the "Gary" who Cookie Monster refers to at the beginning is longtime organist Gary Pressy.)

On final note: The video cuts off a few seconds before it should have. (In fact, all but one video that I was able to track down online cut off too early. Cookie Monster adds something but it's said almost as an afterthought quietly, and I think most people missed it. I thought of embedding that one video, but the sound quality is bad.) However, I was watching the game live, and saw the Stretch as it happened. After Cookie Monster calls out to the crowd to "Let's-get-some....COOOOK-IESSS!!!!!", what you don't see in the video is that a moment later he quietly then says, almost as a second thought -- "...And some runs, too."
