In the nineties, when I was often invited to so called Sportsmens' dinners through my then employer, I remember going to an Ally McCoist testimonial event where Ian Botham spoke. For auction that night was the shirt that he scored his overhead kick v Hibs at Celtic Park in the final of the League Cup. Went for over 3k if memory serves well.
Not more than six weeks later, I was invited to another McCoist testimonial event.
Guess what was up for auction that night?
