Somebody on the Three's Company subreddit (https://www.reddit.com/r/threescompany/comments/1rx2317/comment/ob4v4a0/), recently said that they recall seeing Joyce on Donahue sometime during either the 1980s (post-Three's Company) or early '90s promoting a purported "channeler" (i.e., of ancient spirits). I can't find any evidence right now (either on YouTube (https://www.youtube.com/results?search_query=Phil+Donahue+Joyce+DeWitt) or through Google (https://www.google.com/search?q=Phil+Donahue+Joyce+DeWitt&sca_esv=610e065ca637291f&biw=1235&bih=547&sxsrf=ANbL-n4_oY80JXEZjyMYzAhv0lM11aAgww%3A1773993124006&ei=pPy8aZUDzJPQ8Q_Z0trZBg&ved=2ahUKEwiV5fWv_62TAxXMCTQIHVmpNmsQ4dUDegQIBRAP&uact=5&oq=Phil+Donahue+Joyce+DeWitt&gs_lp=Egxnd3Mtd2l6LXNlcnAiGVBoaWwgRG9uYWh1ZSBKb3ljZSBEZVdpdHQyCBAhGKABGMMESMEdUABY2BtwA3gBkAEAmAGFAaABtA2qAQQzLjEzuAEDyAEA-AEBmAISoAK2DcICDRAuGIAEGLEDGEMYigXCAgsQABiABBiRAhiKBcICBhAAGAcYHsICBRAAGIAEwgILEAAYgAQYsQMYgwHCAhwQLhiABBixAxhDGIoFGJcFGNwEGN4EGN8E2AEBwgIIEAAYBxgKGB7CAggQABgHGAgYHsICBRAAGO8FwgIIEAAYgAQYogTCAgoQIRigARjDBBgKmAMAugYGCAEQARgUkgcEMy4xNaAH4kCyBwQwLjE1uAefDcIHBzAuOC44LjLIB0aACAA&sclient=gws-wiz-serp)) of Joyce ever being on Phil Donahue's show during this time frame.
