The Daning Theatre styles itself an a cappella center, inviting groups from around the world to perform.   The Swingle Singers will be along in May.   The center is impressive; our masterclass and our pre-concert dinner happened on the expansive premises.  We had the impression that there were many musical people in our audience - they were very attentive to all the styles of music represented in "Over the Moon" and we were happy to say many members of the Echo Chamber Choir with whom we had worked a few hours earlier.
