The last time Barbra Streisand appeared on The Tonight Show was in 1963, with Johnny Carson, when she was just 21 years old, and after she had won two grammies for her first album. It’s quite amazing that she returned to the show 51 years later with a new album, Partners, a collection of duets with such legends as Elvis Presley, Blake Shelton and others. This time around, the host was Jimmy Fallon, and Jimmy wouldn’t be Jimmy if he didn’t play some dress up and did a little singing of his own.
