Idina Menzel sings "Take Me or Leave Me" with a lucky audience member

Earlier this month the cast of Broadway's IF/THEN raised money for Broadway Cares/Equity Fights AIDS by auctioning off a live rendition of 'Seasons of Love.'

Now, the cast of IF/THEN has done it again, this time with Idina Menzel singing 'Take Me or Leave Me' with lucky audience member, Sarah Elizabeth Smith, at last night's show!
