WYSIWYG - Thanks for some great ideas, especially on the singing. We can add autoharp and tambourine, and may experiment with that. We have discovered that adding too much "texture" can cover up or detract from a spare but beautiful vocal. Your ideas about the beats, however, are where we need to experiment.

Sorcha - good idea about laying the tambourine on the washtub. I'm curious to see if our bass player will cooperate about attaching one, somehow, to her upright. We've already faked a set of "bones" by using a kitchen knife rubbed over a large carnation creamer bottle. The indents in the bottle made it sound darned close to the real thing !
