And there we were thinking that we'd be left just playing Idina Menzel's holiday album from last year on repeat over the next six weeks! Turns out that the Broadway supernova has recorded a suitably soaring number "Guardian Angels" with opera legend Plácido Domingo for his latest release, My Christmas. Check out below for a first listen of their duet; other artists featured on Domingo's album include Vincent Niclo, Jackie Evancho and Hayley Westenra. It really is that most wonderful time of year.
