Need a Monday morning pick-me-up? Click below for a reminder of just how awesome Idina Menzel’s voice really is. The Tony-winning actress, made a special appearance at New York City Center on July 25 in support of her foundation A Broader Way and stepped up to the microphone to perform “Imagine,” John Lennon’s stirring anthem of peace. Menzel turned her solo into a sing-along halfway through, but her powerhouse vocals are evident throughout. Enjoy this clip while waiting for Menzel’s return to Broadway next spring in the new musical If/Then.
