I thought last years Wrestlemania was very cool how gradualy the lights got dimmer and dimmer leading to the main event. I thought it was uniuqe but then I just watched wrestlemania 3 again and noticed they did the same thing. I popped in Wrestlemania 1990 and they didn't do anything with the lights.

I'm just wondering what other Wrestlemanias did they dim the lights gradualy for the main event? I think it's a good thing to do and adds a lot to the event.
