That is why I suppose Sia. Her face is seldom seen on TV or in performances. I know that there are some early pictures of her but nothing recent.

The other point that I need to make is that the other two ladies are of a different time. There was a thing called MTV.

Today, if a singer has a great song, I will probably hear its cover sang by a pretty (or handsome) little thing first. Or some people will have a better dance move on YouTube.
