Disambiguation Page

Does this need a disambiguation page? I would argue that the other Billy West is not prominent enough to cause confusion. There is not even any article linked for him, and the Primrose article is pretty minor. 
First, I moved this to the bottom of the page because that's where people usually expect new material to be. This way people looking will be more likely to see this question, no biggie. To answer your question; no, I don't think this really needs a disambiguation page for the same reasons that you listed.
