Strauss "Pizzicato Polka" for Triangle, Tambourine and Prepared Piano

Our FEURICH 218 grand piano is undergoing routine maintenance. The dampers are disconnected from the keys and are resting on the strings. The sustain pedal still lifts the dampers resting on a horizontal bar all at once. That's to say, the main change from normal is individual dampers don't rise when a key is played and return to the string when the key is released. So, I temporarily have a piano that can alternate between controllable sustain and a muted prepared piano effect. The arrangement we are playing in this video:
