When I saw these young lasses performing (By the way... they are young to me and I am sure to many of the gripers on this thread) I enjoyed what I heard but some of the people I was with did not. Once again it is all a matter of taste. I would suggest.... that....." These young lasses" have a talent or they would not even get a mention on here....
I would also suggest that there are many women of a certain age that would love to be referred to as young lasses.... so cut the sour grapes and let them enjoy their image... however YOU perceive it.
