Why did Bill Cosby leave Stevie Wonder's recording studio early?

Question

In the episode of the Cosby Show where the family is invited to visit Stevie Wonder, Cliff Huxtable introduces himself to Stevie and then says he needs to leave to deliver a baby. I always thought it was odd that this was written into the script, taking Bill Cosby out of such a main scene. Why did the writers take him out of this scene?

Answer 1

Because he was on call at the hospital. That is why he had to leave early.

Answer 3

Bill Cosby always invited celebrities to be in his show. Remember, it was his show.  Whenever he could, he had them perform by themselves.. like Lena Horne or Stevie or Bo Diddley. He wanted the audience to focus on the guest instead of the focus on him.

That's my opinion.
