Tim Conway is still with us, age 83 — 8 months younger than Carol.
I saw Tim Conway perform live several years ago. He did a number of the routines from the Carol Burnett Show, including his classic "dentist" skit. He had a guy named Chuck McCann with him doing Harvy Korman's role (you would know Chuck McCann if you saw him - he's appeared in numerous TV shows over the years.) He had a young lady open for him who sang and did impersonations (don't remember her name.) She did the Carol Burnett part in the skits.
