Idina Menzel sings the national anthem prior to Super Bowl XLIX between the New England Patriots and the Seattle Seahawks at University of Phoenix Stadium on February 1, 2015 in Glendale, Arizona.

In her performance, Menzel demonstrated just how powerfully she can belt the big phrase-ending notes, drawing out the performance before punching her fist in the air in jubilation as she concluded the song.
