Last Sunday’s Summit of the Stars is still available for free (for now) at medici.tv. But never mind Anna Netrebko’s exciting preview of her Aida, complete with scintillating top C. Fast forward to her “Heia, heia, in den Bergen” and watch her colleagues turn the stage into a dance floor. Then Anna & Co go all schmaltzy waltzy during Jonas Kaufmann’s “Dein ist mein ganzes Herz”. So who’d get the most points on Dancing with the Stars? My money would be on suave Thomas Hampson.
