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 Black, Kermit 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.
