I think a lot of it was nervous laughter. I started off thinking it was in some way a post-ironic pastiche of Bernard Manning and it was going to turn into some Johnny Vegas act, but no, the jokes became progressively more bigoted and appalling, and the penny dropped.
Past nights at the club (Fourth Division Championship team reunion / Woody, Currie & Coloquhoun), they've had the players up on stage, and the mic passed along, so players could reminisce and tell stories from that time, and take questions from the floor.
Not this time, though - instead they chose to put on a crap comedian from Halifax (20-30 minutes or so, seemed much longer) whose only connection with the Blades was he used to watch Tony Currie play for Leeds ! Very disappointing and very very poor. Can't believe Jim Phipps sanctioned this
