Musician Rob Cantor revealed how he faked the impressions in his “29 Celebrity Impressions, 1 Original Song” video. He recorded 11 impressionists for a total of 29 impressions and then lip-synced his way through them.

“29 Celebrity Impressions, 1 Original Song” was created with the help of eleven impressionists and one trumpet player, all exceedingly talented. I hope it was fun to watch, and that you enjoyed my song “Perfect.”
