That is rather a question to address to the CSH Board, and not the Choir, who are as real a bunch as anyone around. The Choir doesn't set the agenda, and so being f'in rude about someone who's giving you a clue is not appreciated.
As it happens, most of the festivals you benefit from would be insolvent if CSH didn't have London rental income from its halls. So get off your high horses and appreciate that an answer's been found to the old problem of getting down to the Library, because most of it's online.
