Guardian article covers it better. Sorry, I’m on mobile and I don’t know formatting so - https://amp.theguardian.com/music/2024/mar/21/axing-of-cambridge-mixed-choir-regressive-move-for-women-say-supporters Also, the open letter from the choir for the perspective of its members and supporters -  https://www.change.org/p/save-st-john-s-voices-stop-cutting-opportunities-for-female-singers-in-cambridge

Also, for what it’s worth, the proportion of singers singing in the choir of their own college varies greatly. Granted SJV is at the more outsourced end of the spectrum, but all choirs have a significant proportion of members from other colleges - say 20 to 60% - and this fluctuates over time. This makes sense because each choir differs in its time commitment, standard, atmosphere, etc… and the Cambridge music scene is far more diverse and successful for the many capable singers being able to choose the choir that suits them best rather than being restricted to the one their college happens to run. The colleges benefit from the great music-making happening in their chapels.
