build up a "history" of each year's performances, choral and orchestral.  I have already unearthed some wonderful Bairstow, Parry (Job of course!*), Stanford, William Harris, Benjamin Dale, Anthony Milner and Dyson. There;s much more hiding away in archive and organists' attics, gathering untimely dust! Do please send me a private EM if you have any info.
www.worldwidemusiconline.com for those who have not yet discovered these treasures!
*remember what George Bernard Shaw had to say about that one?!!!
