Grammy-winning folk duo Indigo Girls have been banned from

performing at Irmo, S.C.'s Irmo High School on May 7 in part because they are

lesbians, Reuters reports. The group had planned to play a half-hour

show there as the last stop on a mini-tour of high schools and universities.

Principal Gerald Witt reportedly canceled the appearance following pressure

from parents and community members regarding the sexuality of singers Amy

Ray and Emily Saliers and the appropriateness of having a rock band play a

school assembly. Witt had no comment on the report when reached at his home

on Wednesday night. Publicists for the Indigo Girls could not be reached by

press time.
