Woodstock (1970) & Woodstock 3 Days of Peace and Music (1994)

I noticed that the documentaries Woodstock (1970) https://www.imdb.com/title/tt0066580/reference/ & Woodstock 3 Days of Peace and Music (1994) https://www.imdb.com/title/tt14097714/reference/ have different pages. It seems to me that this is the same film. And the one marked 1994 is the release on the media of the director's and remastered version. If this is the case, then maybe it is necessary to merge the pages?
