 one of the few operatic works with major roles for  baritone (Scarpia) and soprano as equals (Tosca). It also allowed  McDonald to sing the famous aria Vissi Darte. By the time shooting  recommenced in black and white, this idea was scrapped and replaced  with an elaborate fake Russian opera "Czaritza" created by Herbert  Stothart to music by Tschaikowsky, presumably to allow for a big  Love Duet (in Tosca, she murders Scarpia by stabbing him through the  heart!). The rewritten story of MAYTIME presumably demanded it.  Sadly, the Technicolor Tosca sequence does not appear to have  survived which is a pity as it would have been fascinating to see  McDonald & Eddy in a major operatic sequence and in color.
