Just a heads up for those interested:
GSN is doing a marathon of $25,000 Pyramid from 8am to Noon on Thanksgiving Day, followed by a marathon of The Chase from Noon to 6pm. (Harvey's Feud is on most of the rest of the night, but I'm pretty sure that's just their regular schedule)
The Pyramid episodes, per their on-air guide, are from Summer/Fall 1983.
8:00am: Audrey Landers & Charles Siebert (September 1983)
