It's common enough in folk singing clubs and such for a particular song to be informally "owned" by a member. It'd be unheard of for anyone knowingly to sing it, when a vsitor unknowingly sings it people are a bit embarassed. When the singer has moved away or died they are likely to get mentioned when it's sung, a kind of memorial.

Humans have a way if reinventing traditional patterns of behaviour like that.
