I remember that day quite well. I was on call for radiology and got paged a little more than halfway through the gathering for an emergency case. It was a guy with an acutely occluded left leg artery. A few years later I would be deposed to testify in a malpractice suit filed by that patient against his surgeon. The guys had just started playing 'Smoke on the Water' as I was walking out. Being one of the few Classic Rock fans there, that one was particularly painful.
