"UNCHAINED MELODY" (Righteous Brothers) in extraordinary "remastering!"

An example of audio remastering with superior quality to the original.
Remastering consists of creating a new master, a video or audio copy made from the original, using digital processing techniques, to improve and improve the quality of the previous recording.
In the audio of this 1965 video of the Righteous Brothers (in which Bobby Hatfield sings solo), there was a marked correction of the frequency spectrum (to approximate the current sound quality), as well as greater separation of the stereo channels and noise filtering background.
Note the appearance in the video of a still very young Demi Moore!
Note: Bobby Hatfield passed away in November 2003 for cocaine intoxication.
