Who Are You?

The theme song to CSI: Vegas is "Who Are you?" by a group called the Who.

And it reminds me of the theme song to a local noontime news show on a channel in Philadelphia decades ago.

There theme song began "Who are you, my friend?"

Though I think that if the the CSI investigators ever sing or think their theme song "Who are are You?" they are not feeling very friendly to the criminal they want to identify.
