They also joined in for some of "Single Ladies (Put a Ring on It)," where Beyonce's voice grew stronger. That song featured Beyonce's skilled choreography, as did "End of Time" and "Baby Boy," which also showcased Beyonce's all-female band, balancing out the testosterone levels on the football field.
Before the game, Alicia Keys performed a lounge-y, piano-tinged version of the national anthem that her publicist assured was live. The Grammy-winning singer played the piano as she sang "The Star-Spangled Banner" in a long red dress with her eyes shut.
She followed Jennifer Hudson, who sang "America the Beautiful" with the 26-member Sandy Hook Elementary School chorus. It was an emotional performance that had some players on the sideline on the verge of tears. Hudson also sang live, her publicist said.
The students wore green ribbons on their shirts in honor of the 20 first-graders and six adults who were killed in a Dec. 14 shooting rampage at the school in Newtown, Conn.
The students began the song softly before Hudson, whose mother, brother and 7-year-old nephew were shot to death five years ago, jumped in with her gospel-flavored vocals. She stood still in black and white as the students moved to the left and right, singing background.
