The Westminster Abbey Choir will sing with the Cappella Musicale Pontificia, the Sistine Chapel Choir, in a historic ecumenical event on 29 June that will be broadcast around the world. It is the first time that the Sistine Chapel Choir has collaborated with another choir since it was founded over 500 years ago. The Westminster Abbey Choir will sing music from the English choral repertory including some from the English-language Anglican tradition.
