With October upon us, we can't help but think of Halloween, witches and all other things Wicked. The hit musical's original Elphaba, Tony winner Idina Menzel, is quite the busy lady these days as mother to her one-year-old son Walker (with hubby Taye Diggs), filming Glee guest spots and flying across the country perfoming solo concerts. On October 2, Menzel landed at the Tilles Center for the Performing Arts in Greenvale, New York for a concert, in which the former Rent star broke out a slowed-down rendition of "No Day But Today." Take a listen to this beautiful performance, and don't be shy when Idina invites the audience to sing along at the end! (To see Idina live for yourself, check out her website for upcoming tour dates!)
