"Employ" SO? Fire them if you can.
"Own" the Beeb? Cancel their next fine/court case for non-payment of licence - if you can.
Too many degrees of separation in those relationships to have any meaning at all.

But why bust a gut to persuade the Beeb and SO to do "the right thing"? Why does it matter? Neither is an authority on what is "traditional", after all. Yes, the media have the power to influence the masses into believing Seth's song is "trad", just as they have the power to influence them into believing that the next "celebrity" they manufacture is worth watching in some so-called reality show.

But we were never in folk music for the sake of what the masses believe, were we?
So why bust a gut?
