Many thanks to Chas Clifton for forwarding this article to me. Taki's Magazine details the mysterious figure of Del Close and his connection to both the national comedy scene and witchcraft.
"From the late 1960s until his death in 1999, Close taught long form at
Second City Toronto and Chicago and served as SNL’s “house
metaphysician.” No wonder the names of his other devoted disciples read
like a comedy hall of fame: Dan Aykroyd, John Belushi, John Candy, Andy
Dick, Chris Farley, Shelley Long, and Gilda Radner, to name a very few."
