Always found his contribution to the show unique, valuable, and most welcome. I wish we had seen him in other important roles in the years after the two MASH series. He must have done a lot of guest star work, but was he a regular on a hit show again?
At any rate, my deepest sympathies to his family and friends.
This gentleman was a vital component of a production for the ages. I know little about his personal life, but he certainly enriched mine with his spirited portrayal of Father Mulcahy.
