Tonight’s new installment of David Steinberg’s wonderful talk show about comedy features two brilliant performers who, like him, developed their chops at Second City: Fred Willard in Chicago, Catherine O’Hara in Toronto. In the Seventies, they starred in two of the most hilarious low-budget TV shows ever made, both of them syndicated: Willard in Fernwood 2-Night, O’Hara as one of the founding members of SCTV. Covering their careers since then could easily fill separate full-length documentary salutes, so as Steinberg chats with them both during the same half hour, strap in and hold on.
