Ah, Dartington! The simple answer is ALL. I'd also be inclined to use Child, rather than Childe - more comprehensive.

I suspect different singers will give you different answers about the rest - largely because there are different motivations for performing this stuff.

Not helpful, I know, but the subject as defined in your posting is too huge for a degree discourse - I'd recommend narrowing it down - A LOT.

Good luck - and keep fighting the move to Totnes. Might be useful to meet up some time - we're at the other end of the County, but sometimes down your end. Try our website at www.umbermusic.co.uk
