The Oinker Sisters.
Cheryl E. Hardwick (b. 1944)[1] worked as a composer for Sesame Street and performed the voice of one of the Oinker Sisters and one of How Now Brown's Moo Wave cows. She was part of the team of Sesame Street musical personnel that won the Daytime Emmy for Outstanding Achievement in Music Direction and Composition in 1990.
She has a master's degree in piano performance from The Juilliard School, a skill that earned her the distinction of being the first female member of the original Saturday Night Live band. She later became the musical director on the show from 1986 until 2000, and was married to Saturday Night Live head writer Michael O'Donoghue until his death in 1994.
