I tried looking and couldn't find the information here or online but for some reason its bothering me. I know the 80's run of Pyramid usually had the same light-up sequence with the trilons where its Bottom lights on, plus middle lights on, plus top lights on. I've found mention that on the Clark $25k Pyramid that for a couple weeks they changed it to Bottom, then middle (bottom off), then top (middle off). I thought, though, that the Davidson Pyramid run did this at one point too... I can't find any proof of this but I figured somebody here may know. I tried finding clips on YouTube but didn't see anything.
Thanks!
