I'm not sure. It may have been a little later as I think we were in limbo for a little while. Looking back at the fixtures, the Liverpool game was on the 2nd December and I think Kendall's first game in charge was Norwich at home on Boxing Day, although upon reflection I do remember him going to watch us at the Dell on the 9th before he was appointed so it doesn't make sense (even for Swales!) offering the job to Joe (which was on a Friday night iirc) after the Liverpool game, so you're probably right. I remember Joe citing the reaction of the tea ladies at Oldham as a reason for him staying - how times change!
As to your all too kind comments about my delivery, I'm not sure you're entirely right. My oral style has (thankfully) developed a little more finesse since 1989!
