This album was a blockbuster even before the movie SATURDAY NIGHT FEVER was released in theatres on December 16,1977. The CD version was originally a 2-disc set,which I own. It's equivalent to the 2 LP set. When the digitally remastered version was released it became a single disc because the entirety of this album totaled approximately 77 minutes. The Bee Gees' previously released YOU SHOULD BE DANCING and JIVE TALKIN' appear on this album. Originally,the live version of JIVE TALKIN' taken from the Bee Gees' HERE AT LAST LIVE album was on this album. My CD copy has the studio MAIN COURSE version. YVONNE ELLIMAN performs the Bee Gees' composition IF I CAN'T HAVE YOU. Original Bee Gees' songs are STAYIN' ALIVE,HOW DEEP IS YOUR LOVE,NIGHT FEVER and MORE THAN A WOMAN. Tavares' cover of MORE THAN A WOMAN is on this album also. Another previously released song is Walter Murphy's A FIFTH OF BEETHOVEN. We hear Kool and the Gang performing OPEN SESAME,K.C. and the Sunshine Band doing BOOGIE SHOES,and the Trampps' DISCO INFERNO. This was the biggest-selling movie soundtrack album next to the GREASE soundtrack. John Travolta made his starring debut in the film,when his TV show Welcome Back Kotter was in prime-time. Travolta is seen on the front cover of this album on a multi-colored dance floor wearing the white gabardine suit like he did in the film. Behind him stands a photo of the Bee Gees. What a beautiful combination,huh?
