Some singer named Rob Cantor came up with a pretty clever way to promote his new album.  He does impressions too, so he recorded himself singing a song called "Perfect" . . . as 29 different celebrities.

 

He starts as Randy Newman, then does Jack BlackKermit the Frog, and Louis Armstrong.  He also does a bunch of FEMALE celebrities, like Gwen Stefani and Christina Aguilera.

 

And THOSE impressions are so good, it almost seems like he dubbed in a WOMAN'S voice.
