Improvisation on Jerusalem

I have to play about 5 minutes of mood music in my current gig, and given my full-time job, I don't have time to learn prepared pieces every week. Here's Cavaille-Coll going all British on you (of course) on this great tune by Parry. You'll hear I pop the cres. pedal too much at one point--but then again there are no re-do's when improvising. Cheers,
