Some funny stories there folks - I guess I posted because I'm laughing at myself as much as anything.

It occurred to me that my dynamic of bonding with a song (and thereby putting me own signature on it) and then feeling an awkward possessiveness of it could be part of the "shared unconsciousness" - I'm not particularly unique.

My being proprietorial is purely an emotional experience, because my intellect (which wins out) informs me that trad songs belong to everyone!...and if you love something set it free.....

It seems to me that folkies have all sorts of unspoken rules; it can be quite amusing/interesting when others are oblivious of them and breach a code - don't need to look past session behaviours for that..
