In memoriam, Katherine Grayson and Frank Sinatra in 1947’s It Happened In Brooklyn, singing “Là ci darem la mano” from Mozart’s Don Giovanni. Make fun of it all you want, I still think this is forty kinds of awesome. The pianist is André Previn; somewhere out there is an alternate take with Previn and longtime MGM stalwart Johnny Green manning two pianos, just to further mess with the purists.
