Wrestling detective wanted. Apply within.

Not sure if anyone can help me with this one. I’m trying to find a bill for the first ever live wrestling event I attended. I know it was at Fairfield Halls around 1975 - 76. I also know the main event was Kendo v Prince Kumali and I have a feeling The Royal Bros were also on the bill but I could well be wrong about the second part.

Are there any sites I could search ? or does anyone by the name of Adrian possibly even own a poster?

Seriously doubt anyone can help, but the things that get pulled up on here never fail to amaze me.

Thanks.
