Marcus Welby, M.D. S04E11 - Jason Be Nimble, Jason Be Quick

The good doctor Welby deals with arthritis to a boy and the lad's estranged parents. Welby's main job is to prevent the boy's father from running off again, avoiding responsibility, and star Robert Young, does the persuading with his customary charm and logic. The show is well cast, with James Stacy in the role of Dad, on the run.
