I believe the Choir of Trinity College, Cambridge is comprised of males and
females. I read that women began being admitted to the college in 1982.
The choir is made up of 21 undergraduates. There are 9 sopranos, 4 altos,
4 tenors, and 4 basses. I believe the women are in the choir or at least
there have been women in the choir since 1982.
