Sandra Schaeffer (Bergeson), born in 1946, is a singer, author and game inventor, and a 1968 graduate of North Central College in Naperville, Illinois. Sandra is famous in her earlier adult years for having replaced Madeline Kahn in the late 1960s off-Broadway musical phenomenon, Promenade, which later went on to become a cult classic in Broadway circles. She was one of the first college students ever to be hired into the chorus of the Lyric Opera of Chicago (before the College programs that are now offered there) as an alto and then went on to The NYC Opera of Lincoln Center as a Soprano. She was specially chosen amongst a small group of women from the NYC Opera to sing in a Spanish ``Zarzuela'' at City Center directed by Tito Copobianco. She was selected as a finalist for the lead in Broadway's Man of La Mancha & Two by Two by Richard Rogers.
