"Why should folksongs be different."
It's not who writes them Al - it's what happens to them after they are written that makes them 'folk'
I'm never sure whether 'Greensleeves' counts as a folksong with anybody, it does with some - it has been suggested that that was written by Henry VIII
He is certainly named as having written 'The Hunt is Up'
Amazing what a bout of STD does for creative inspiration !!
