It’s her only day off and Idina Menzel is holding a one night in concert at Radio City?! This star is the epitome of a hard worker! If there was an award for being the hardest working gal on Broadway, then Idina would, without a doubt, win that one! The Frozen star’s schedule is totally booked due to her new Broadway show, If/Then , where she performs eight shows a week with only one day off! But on June 16th, she’s foregoing that off day for an epic one night concert starring herself!
