These are the files most users want: a direct VHS rip or DVD transfer of the 1978 movie. While these files do appear sporadically on Archive.org, they are often deleted by administrators due to copyright claims from Paramount. If you find a live link, it may be low-quality (240p or 360p) and might disappear the next day.
Search for “ Grease 1978 TV special” or “ Grease premiere news.” The Archive has digitized segments from shows like Entertainment Tonight and PM Magazine featurettes showing John Travolta learning the hand jive or Olivia Newton-John transforming into “Bad Sandy.” grease 1978 archive.org
