I hate to be cynical, as you may know it's not at all like me to do that!! However the BBC has always only ever paid lip service to authenticity with it's eye on the ratings charts as the main driving force.
I daresay most of us could put on a better selection of artists, and chosen more stirring and representative pieces to broadcast.
At the end of the day the people who make these programmes have only ever heard of a few folk artists, and thay keep going back to these people every time.
They of course don't want to turn down the cash so the lesser known albeit oftimes better performers don't get a look in.
It is now and always has been, 'If your face fits', and do you really think you'd have had a chance of seeing Eliza on this programme if her father had been Joe Bloggs from Nowheretown.
Do yourselves a favour and listen to /radio/aod/scotland_aod.shtml?scotland/travelfolk"> Travelling Folk on radio Scotland where you will get a better mix of talents, and not the same old same old that these programmes polished the egos of.
