I'm going to bend my rule of featuring only songs completely in Italian for my song of the week, but as I'm in Italy it's all good. It's a duet by Mika, my favourite singer; and Chiara, who won X Factor Italy last year. It's a beautiful bilingual version of Stardust, from Mika's third album The Origin of Love. They first performed the duet together on the show last year, when Mika was a mere guest. This year he's one of the judges and they performed the song together again on last week's show. It's been No.1 on the iTunes chart in Italy for several days since its release; as well as the album that contains it, Mika's Songbook Vol.1, which contains his singles to date, and has only been released in Italy.
