After the 1977 Royal Variety Performance, Charles was hugged by Muppet monster Mean Mama. That year, David Lazer invited Charles "or his representative" to the ATV Studios to watch a taping, and consider appearing as a guest on the program, saying he understood "if his schedule —or protocol —prevents him." Charles would have received full script approval. Kermit himself also pitched an appearance. In 1986, he and Diana attended the Labyrinth Royal Command Premiere.
