Other acts in the Cabaret

To me the term "Cabaret" means nightclub. This film is attempting to show us the decadent world of the Weimar Republic Cabaret which was apparently a different thing.
At the end of the Wilkommen song, Joel Grey introduces the audience at the Club to the performers. It does by really fast, including his mention of Sally Bowes, but there seems to be a ventriliquest, someone with a strange hat that looks like a tinker toy and some others but the camera angle is so wierd you can't really see them. Aside from Sally Bowes and the MC doing his bit with the girls, what do you think the other acts were?

I imagine this was done to show that the Cabaret was not like Vaudeville where many acts of different kinds were shown one after another in a performance.
