David canary played Candy Canaday, the Ponderosa Ranch hand from 1967 - 1970. David quit due to the fact that he didn't have equal billing rights with the other regulars among other contract demands that were termed "unreasonable" by producer David Dortort. He rejoined the cast imediatley after the sudden death of Dan Blocker in 1972. Dortort wanted the veiwers to have a farmiliar face to relate to and this time Candy would have equal billing along with the rest of the cast. He was on the show until the end in 1973.
