Barbara Streisand was simply amazing last night at the Wells Fargo Center in Philadelphia. It was a big night as Barbara's son, Jason Gould, joined her on stage to sing live for the very first time. Wow, the apple does not fall far from the tree! In addition, Il Vilo performed to the delight of everyone in the audience. When they finished their set Barbara came out and said: "Take that Justin Bieber!" - to the roar of the crowd.
