William Redfield : Television commercial he appeared in?

Television commercial he appeared in?

Does anyone remember the anti-smoking television commercial William Redfield was in around 1971? A short version and a long version would play on TV every so often.
He played a character trying desperately to find a place to light up. Everytime he tried someone would point to a no smoking sign or scold him in one way or the other for doing so. Sid Melton (Alf Monroe in Green Acres) played the cabdriver refusing to allow him to s 5b4 moke in the cab.
