For those wondering about Saturday Night Fever since the 30th anniversary is coming up ITTL and the 45th will be in December 2022 IOTL.
ITTL, the R-rated version came out first in December of 1977. The T-rated version came out about 18 months later due to MPAA rules at the time which dictated that a film had to be out of circulation for three months before an alterate version can be made available. The T-rated version keeps about half of the language and violence, but the rape scene is taken out. In 1980, HBO aired the R-rated version only at night - due to network policy of the era - while the T-rated version ran during the daytime. In the years since the theatrical release of both versions, Paramount has made both available across most physcial home media formats including recent VHS reissues licensed to Limited Run.
How "Manhattan Skyline" became the signature anthem for the NHL in the United States.
Of course, David Shire's "Manhattan Skyline," which was featured in the film's soundtrack, was later used by SBC as a de-facto theme song for the first five seasons of Wednesday Night Hockey (1980-81 thru 1984-85). For the inaugural telecast, which pitted the Los Angeles Kings against the New York Rangers at Madison Square Garden on October 8, 1980, the song was meant to be a placeholder before an original theme could be composed. But the feedback from fans proved positive enough that SBC made arrangements with Shire and his record label to allow the song to be used on NHL telecasts full time for the next five years. Very quickly, "Manhattan Skyline" became synonymous with the NHL among American sports fans. Soon, every ice rink in the States felt the need to keep a record of the song handy for youth, high school or college games. And eventually, kids and adults who played tabletop or bubbletop hockey began humming the song as they turned the knobs. In 1982, Stiga used the song for a commercial for a Wednesday Night Hockey edition of its famed tabeltop games.
In 1985, SBC abruptly retired the song in favor of borrowing music from CBC's Hockey Night in Canada. At the time, SBC cited a larger cultural shift away from disco as the reasoning for the sudden shift. A year later, David Shire sued SBC because the network did not tell him ahead of time that they were discontinuing the use of his song. By 1988, Shire won a settlement in which he could still get the royalties he enjoyed before whenever SBC would bring the theme back for special editions of WNH. In 2006, after years of additional litigation, SBC brought the song back full time to WNH.
