The actor, singer and comedian, best known for playing Good Times building superintendent Nathan Bookman, died last Wednesday at age 84. "Such loving memories of our time together," tweeted Jackson. "You were full of laughter and forever smiling. Always so sweet and so kind to me. I love you and will miss you." On Instagram, Stanis wrote: "I am devastated to hear about my dear friend Johnny Brown who played Bookmen on our show Good Times. I will miss all the stories about Sammy Davis Jr. Frank Sinatra, Dean Martin and even John Wayne. His talent was beyond measure…. He was such a pleasure to work with. I certainly will miss his happy spirit and big smile. Praying for his family in every way."
