Hi, the version you posted is from Earl's Court 77 and it was just a part of Rock'n'Roll Medley, so we could say it's complete there. Queen played it usually as an intro before Bohemian Rhapsody or as a short part of the medley so the average length is about one and one and half minute. But I've got 3:25 long mp3 version in decent quality from Osaka May 15, 1985, so I can upload it if you want.
