Yes, I see what you mean, Allan and Nick. I agree. I did ask for a reason, well two really. Primarily, if mainstream singers do folky stuff then it may become both better known and more acceptable among the younger generations. Of course we may get some critics slagging them off but that always happens. Secondly, I was once told in no uncertain terms that pop singers can never do folk as they are only in it for the money and any folk singers trying out new stuff are just wannabee pop singers. Good to see that attitude is not endemic :-)
