Fitz Choir - Recording confirmed

I've just got an e-mail confirming the recording of Fitzwilliam Choir.
I will record their rehearsal in Fitzwilliam Chapel this Saturday. Hopefully, one of their pieces will be suitable for my portfolio. As far as I know the acoustics of the place, the array of 2 coincident cardioids angled 180 degrees should do the work.
I already booked Marantz digital recorder and a pair of AMG C414s to borrow for a week-end, so everything seems to be ready to go.
