Michael Bublé was in the house and got the spirit of Big Band Week started with "You Make Me Feel So Young." This theme makes us feel so young. The judges were on their feet throughout the performance, and Kelly Rowland was singing along and hugging Demi Lovato. Michael worked with the acts this week, and he said it was a great pleasure, adding that everyone brought something special. Did they bring green bean casserole or candied yams?
