I've been meaning to mention to online audiophiles, you may wish to look at some of the programming available online at the BBC. Two programs strike me, which you don't have to catch live as they are made available in full, including a number of the programs from weeks before. Those two programs are:
Choral Evensong. The most recent program was from Christ Church Cathedral, Oxford, the week before, Eton College Chapel. Always worth a listen to the beautiful polyphony and chant.
The Early Music Show" is another one that people might have an interest in.
