Pipe Organ
From Muppet Wiki
The Pipe Organ belongs to Count von Count on Sesame Street. Though often a featured prop and significant part of the Count's castle, in recent seasons, the pipe organ became a character, joining the Count in the "Number of the Day" segments, as each individual pipe would open its eyes and sing according to its number.
Among the performers of the pipes are Fran Brill, John Tartaglia, Stephanie D'Abruzzo, Martin P. Robinson, David Rudman, and Joey Mazzarino.
