In a rather lengthy video interview (during which she goes, "Ummmm" a whole lot), Kay Alden says that in the early months of Y&R, Bill Bell was utilizing two or three --- "ummm, I think it was two, ummmm maybe it was three" scriptwriters on the West Coast. According to her, both of them (or all three of them) quit about the same time in late 1973 or early 1974. This was shortly after she'd submitted a few "spec scripts" to Bell, which he'd paid her $50 each to write, even though he considered her scripts to be somewhat amateurish and overwritten. When the West Coast writers quit, Bell called her on a Friday and said, "I'm offering you a job and need for you to begin next week."
She goes on to say that their "breakdown sessions" consisted of herself and Bill sitting down together in his apartment on Lake Shore Drive every morning. He would jot down a few ideas on a stenographer's pad, discuss the ideas with her in a bit more depth, then tear off the page, give it to her, and she would immediately begin penning the dialogue. By 5:00 p.m., she'd completed the script and Bell had reviewed it, made any changes he wanted to make, packaged it up, and had it ready for a courier service to pick up the package for overnight shipment to Los Angeles. She said it was a harrowing process (having to be finished and ready for delivery by 5:00 pm every day), but it was how they rolled for many, many months, with herself and Bell exclusively handling the scripting of each episode. But she says the rewarding aspect of it is that she and Bell developed a symbiotic relationship in which they could practically read each other's minds and always knew exactly what was expected of each other.
(And in retrospect, this is probably the ideal method of scripting a thirty minute show. There's no misunderstanding between the head writer and the script writer, as the two of them are sitting by one another all day, can talk freely and ask questions, and can tweak things as they go. It's no wonder that the scripts were better -- and clearer as to character development and motivation -- while she and Bell were working together in this manner.)
