Armistead wrote a tribute on his facebook page:
“In the original "Tales of the City" (1993) Donald Moffat played Edgar Halcyon, a dying businessman who has one last chance at romance with Anna Madrigal, the transgender landlady of 28 Barbary Lane. The kindness and gentle strength he projected in that role was very close to the demeanor of the man himself. We adored him on the set, especially Olympia Dukakis, who had suggested him for the role. I shall always be proud that I knew him.”
