I googled Eartha Kitt, who died the other day at 81, AND Laura Nyro and, frankly, didn’t come up with any significant links. So I’ll have to suggest two of my own:
1) Both were iconoclasts, refusing to stick to the well-trod path carved for women performers.
2) Both had a great sense of humor. Check out the song above to see/hear just one example of Ms. Kitt’s. As for Laura, her funny side didn’t usually show on stage, at least in her early days of performing when you could hear a pin drop if she paused mid-song but nary a laugh at anything said or sung. By the late 1980s, however, she had written and frequently performed an entirely humorous song, “Japanese Restaurant”–how about that! It never ceased to draw laughter, especially when she told the waiter that she’d given up smoking, so now she wanted a big bowl … of chocolate ice cream.
