I do think that quoting performances on Utube is a bit unfair.These are put there free of charge for others to listen to.They are normally home made performances and not studio recordings.OK some use them for promotion of themselves,but mostly it is a bit of fun,with beginners attempting to perform in public for the first time.The same applies for Folk Clubs a scared person gets up on stage in front of an audience to start off a possible Folk career.All performances no matter how bad are accepted ,they get applause and from that beginning we get many of the big stage names we know today.If a great big hook yanks them off the stage a minute into the act or someone shouts out "It's Crap ,get off the stage" then that performer will never be seen again.
The latter will be the way to kill off all future talent.
