Palpatine mocking Yoda, was it filmed?

As all of you know, the SW novelizations are based on the shooting scripts, therefore they include a lot of content not seen in the films. In Return’s case, during Palpatine’s confrontation with Luke he asks if Yoda is still alive, mocking his speech patterns in the process. We know some content is cut prior to shooting, so what’s the case with this scene, were those lines ever spoken on the set?
