Spoiler alert! At the end of her two-hour, high energy Chicago stop of her I am… tour, Beyoncé Knowles completed the “I am…” sentence by telling the crowd “I am yours.” And she wasn’t kidding. Beyoncé gave it her all at the concert, singing just about all of her singles—including many Destiny’s Child hits—starting with the chart topper “Crazy in Love.” It was the perfect song to begin with, and it let the audience know that it was in for a non-stop dance party. There were a few slow moments. Beyoncé sang “Smash into You” in front of a giant screen displaying crystal blue waves, making it look like she was under water, she performed  “Ave Maria” and Sarah McLachlan’s “Angel” donning the same avant-garde wedding/first communion dress she wore at the BET Awards and toward the end of the show she belted out “At Last,” and showed clips of Obama’s inauguration (as well as video of her performing the Etta James hit for the President and Mrs. Obama at an inaugural balls). The rest of the show was all about the crowd dancing and singing along while Beyoncé performed another ’90s cover (Alanis Morissette’s “You Oughta Know”) and blasted through cardio routines that would wind Madonna.

Halfway through the show, she literally lept off the main stage and flew to the ceiling of the United Center (spinning, flipping and lowering to make it look like she was gently walking on audience members along the way) before landing on a smaller stage in the middle of the floor. It was there where she sang the classic Destiny’s Child song “Say My Name.” Before singing it, though, she asked an audience to say his name. The starstruck fan was freaking out that Beyoncé was talking to him. He could barely say his name (”R-r-r-r-r-ooooob!” was his response) and then almost fainted when she started the song and sang his name a few times. (Here’s the magic moment on YouTube.) Later in the show, “Irreplaceable” became the ultimate audience singalong, and “Single Ladies” started with video clips of fans (as well as Justin Timberlake and his SNL cohorts) mimicking her now famous dance.

Beyoncé ended the show with an extended version of “Halo,” shaking hands with fans in the first couple of rows and bringing two small girls onstage to sing along and pose for a picture. She interrupted the song to pay tribute to Michael Jackson (I expect every pop show will involve an MJ tribute this year), showing a video clip of a 5-year-old Beyoncé and her mom getting ready to attend a MJ concert in the mid ’80s. Before she left the stage, she asked if anyone was celebrating a birthday that night and half the audience raised their hands. “I suspect some of you aren’t being truthful,” she joked, and even though her voice started to sound a little strained (proving she wasn’t relying heavily on pre-recorded tracks), she then broke into “Happy Birthday” with all her might.
