Wow that sounds amazing! I love madrigals and things. I was really lucky when I was at school to be in the Chamber Choir and we made a CD (that actually went on sale to real people too!) and it was called Song through the ages. Loved it, we sang songs right from madrigals to much more modern things.
I haven't been involved in any singing since I left teaching about 10 years ago now.. Really should think about it..
