True, as the previous reviewer states, many of these "Disco-Version" cuts simply had looped pieces "edited-together" to make it appear as a longer version, some of them hastingly done, but not EXTREMELY poorly done. Case at point, "Stayin' Alive" actually featured a slightly different mix, at a slower speed (oddly enough, since it is billed as a Disco Version, whereas most disco versions are speed-up). In the this mix, the sound level of Barry Gibb's acoustic guitar is lowered drastically and a horn vamp is bought in at where the first vocal bridge-refrain is normally at. Also, where the songs normally fades, at the beginning of the 4th ending refrain, the second part of that refrain is completely edited out, and the "horn piece" is brought back in a second time, via an loop-edit.

Next, "Night Fever" is slightly speed-up and has simple edit-loops done to create a longer version, of about a minute or so, some of the edits sounding sort of "hacked" and "chopped" poorly.

"More Than A Woman" is also speed-up very slightly, uses the same kind of editing/extending technique of "Night Fever", but if one listens to the VERY END of the fade-out, the song uses an slightly alternate mix of the vocal track; Barry's add-libs are more "up-in-the-mix" than the album version. (On a side note: The version of "More Than A Woman" that was featured in the actual film, during Travolta & Gorney's "Love" dance on the floor, features a very beautiful & lush alternate string arrangement on the SECOND verse only. This take was NEVER released on any audio recording medium, as far as I know).

"If I Can't Have You" used it's traditional speed, but featured an EXTREMELY BAD edit to cut back in the horn & string musical bridge, for a second time. The edit was SO BAD, it cut into the whole timing of the song and clipped out a whole half-measure. The editor of this track CLEARLY does understand the timing a rhythm section keeps while recording!

Lastly, "You Should Be Dancing", features the same version that was released previously on a 12" DJ/Radio-Only Promotional Record. Like "Stayin' Alive" this version was slowed down a bit (oddly enough), but received the same mixdown as the traditional version on the "Children Of the World" album, EXCEPT the album version contained 1 refrain in the first chorus, 2 in the second and 2 in the third, whereas this "Disco Version" features 2 refrains in the first chorus, 2 in the second and 3 in the third! All of which, where not "falsely" edited in as loops, but were actually "edited-out" of the official "Children Of The World" album version! This I quite never understood, why producers Richardson & Galuten did this, but it sure made for good critical reviewing & listening, of this AND all these "slightly" different "Saturday Night Fever" cuts & versions.

If you haven't heard the special disco versions, here's some info : only the version of Staying Alive is a different version : an extended version with added horns. Nicely done btw. The other mixes are disappointing, I'm afraid : in order to extend the songs, parts of the songs were repeated and erm... glued together so to speak (and not always in a professional way!!)...
