Mary Kay Bergman

Mary Kay Bergman, also known as Shannen Cassidy (June 5th 1961 - November 11th 1999), was a voice actress who served as nearly all the female voices of South Park from the aired version of "Cartman Gets an Anal Probe", all the way to "Hooked on Monkey Phonics". Bergman used the Cassidy alias for her work on South Park as at the same time she also performed voices for Disney. She was seen in the 1998 Goin' Down to South Park documentary discussing her voice work and practicing several voices. Bergman battled with depression her entire life and committed suicide November 11th, 1999. Recasting was held off and as a result the female characters were seldom used at the end of the third season, and her spot at the Oscars to perform "Blame Canada" was replaced by a performance of the song by Robin Williams. She was paid a brief tribute in Mr. Hankey's Christmas Classics, when during the final song the lines "Here we are in olden days/Happy golden days of yore/Faithful friends who are dear to us/Gather near to us once more." Clips are seen of the female characters before Stan and Kyle are joined by Wendy Testaburger, Shelly Marsh, Sheila Broflovski, Liane Cartman, Carol McCormick, Sharon Marsh, Principal Victoria, Nurse Gollum, and Veronica Crabtree, though none speak. Before the fourth season began, the roles were recast to Eliza J. Schneider, except for Ms. Crabtree and Sheila Broflovski, who were taken over by Mona Marshall.
