There are a lot of female impersonators out there, but surprisingly few female impressionists. And fewer still with the vocal talent of Carly Sakolove. Soon after Bernadette Peters replaced Catherine Zeta-Jones in the Broadway revival of Stephen Sondheim's A Little Night Music, this little video — really a song with slides — made the rounds among the musical theater cognoscenti. With spot-on vocal imitations performed in one take by 24-year-old Sakolove, many of Broadway's best known Divas — from Peters and Elaine Stritch to Julie Andrews and Judy Garland — each sing a few bars of Night Music's signature tune, "Send in the Clowns." Isn't it rich?
