My parish used to have a fabulous music director who did manage to actualize "the concept of community celebration." She was an absolute genius at getting a congregation to sing, "lustily." Utterly transforms one's experience of liturgy. She was so appreciated and loved by our then liturgically-savvy pastor and our congregation that we bent over backwards to work out a full time position for her when she felt she might need to go. And when she expressed a desire for a baby grand, funds were raised within three months precisely because it was her desire. 

Visiting priests, and a bishop, tended to complement their musical experience with us by calling us Protestants.

New pastor; not sympatico with music director; so she had to move on. Our loss became a local Anglican community's gain.
