We know John Mayer has a thing for old women women of a certain age, and this time he has done Mariah Carey.  Ok, he covered the Mariah Carey song All I want for Christmas Is You.  But it’s not hard to imagine the other is it.

The cover took place during the recent benefit concert at Blythedale Children’s Hospital in New York.  You can check out the footage below.

John Mayer reads all his press during regular google vanity searches so to John Mayer, a hospital benefit concert before Christmas, maybe you aren’t the complete ass we all thought you were.  Also we are bored with the whole Manniston thing, do something about that, ok?
