Can you help identify my first ever wrestling event?

It was between 1991 and 1993 I think. I was 12-14 at the time. The few sporadic details that I remember are that the star of the event was Alan Kilby. I think he was in a tag match with a young guy. There was a big fella (heel) who was very mobile and took a hell of a bump to the floor near me during the battle royal finale (I think Kilby dumped him out to win). I don't remember much more than that unfortunately.

I know its not much to go on but does anyone have any ideas what the card might have been, what the date might have been?

I'd really appreciate any info you guys can give.

Edit: Oops, forgot to mention that it was in Walthamstow.
