John Travolta in Saturday Night Fever, 1977. When I saw this in 1977, I thought it was the coolest thing ever! John Travolta's dance moves were so."bad!" Now, I realize, they were just plain bad. ;) #toomanyspoofs
Saturday Night Fever, The Bee Gees + Various Artists, 1977. Interestingly, while Saturday Night fever has a pumpin' soundtrack, it's a pretty grim, urban film. Aesthetically the cover is revolting but it sold a bundle.
