In June of 2006, Keith starred in the play The Island, written by Athol Fugard, at the Contemporary Stage Company in Wilmington, Delaware. Sean Patrick Thomas starred with him as well.
Keith: (About getting cast in 30 Rock) I was working on my theatre company in Delaware. I had a meeting with an agent about a designer. I had gotten friendly with the agency over the years because I hired some of their designers. They asked if they could submit me for this television project. I said, 'Sure.' When I got the sides for 30 Rock. I said, 'It's my part to lose.' I knew the character very well. Thank God, they agreed.
Keith: (When asked about relationships in his life) I've always been curious about how relationships last for 40 years. My relationships haven't lasted very long, or I'd be married now. To be quite frank, in the family I come from, that's never happened, with one exception. I have a great aunt, my grandmother's sister, who's been married 50 years.
Keith: I'm kind of a workaholic, I've always been able to provide for myself an environment where I'm busy, working in the theatre or in the profession that I love.
