The Sidney Sussex Choir of Cambridge University are performing on the Island this weekend.
It's thanks to alto Giverny McAndry - a former student of King William's College, and second year music student at Cambridge.
Today, the college choir will be hosting a joint rehearsal with the Giverny's old school choir, and later performing for the public in the chapel at 6.30pm.
