"Today we lost a damn good man a father and and great actor," Harmon wrote. "Here's to you TA. We shared many glasses of Vino Rosso together brother. I'll never forget how excited you were to land B&B. By the way you still owe me that lobster dinner. I'll collect next time I see ya. We will will miss you my dear friend. RIP. I know you're walking the streets of Gold bringing joy to the Angels as you did here on earth. God Bless you man. Love and miss you brother."
