Floating in cyberspace for the past 10 or so years is an old grainy video of Mario Del Monaco singing Musica Proibita by Stanislao Gastaldon on the Ed Sullivan Show in 1958. The original video was slightly slower which made the audio a semi-tone lower. The audio itself was over modulated and filled with distortion. About 30 years ago, I purchased a CD in Italy which had a better quality reproduction of this performance which always made this video difficult to watch.
With a little effort, I was able to put together this video with the improved audio. Synching was a big issue since the source video varied 2-5% in speed – which forced me to break the video into small slices and “tweak” the speed every few seconds.
