Looking back, we can see a few definite categories when it came to booking celebrities on MG/HS:
Hot Chick: Usually one per week. A mixture of series stars (Rebecca Holden, Lydia Cornell, Audrey and Judy Landers), relative unknowns (Twyla Littleton, Christie Claridge), and Playboy playmates (Vicki McCarty, Karen Witter, Shannon Tweed). Also Martha Smith, who fit two of those categories.
The Comic: Some of them had done CBS/syndie MG. Phil Proctor, Fred Travelena, Arsenio Hall, Marty Cohen.
NBC Insisted: Their series stars, who appeared in far greater numbers than on the '70s versions of either show. Leonard Frye, Bonnie Urseth, Tom Villard, Nedra Volz, Kim Miyori, various soap stars.
