Of course she can sing.
As far as I am concerned different styles of singing are what make traditional and contemporary folk singing interesting, whether people like a particular persons style of singing is always a matter of taste.
when people post on this forum and start saying things about other singers[such as can they sing?. or she shames the whole folk scene, or any other slagging off of any singer, WHOEVER that is] it is in extremely bad taste, and shows the petty minded nasty nature of those who do it,vindictive, bad mannered, unpleasant people.
