A "pan & scan" version was broadcast on Spanish Castilian TV showing the movie cropped to 1.85:1 and only musical numbers (and credits) were shown in it's original 2.35:1.
1998 theatrical re-release featured a heavily remixed soundtrack. Reverb and, in some cases, background vocals were added to many of the songs, and new sound effects were added in certain scenes. All DVD and Blu-ray releases up to 2018 feature only this remix. The 40th Anniversary 4K, Blu-ray, and DVD restoration contain a remix of the original stereo soundtrack, restoring all of the original sound effects and undoing all of the revisions (most notably the background vocals) to the songs from the 20th anniversary version.
All pre-1998 prints of the film feature the then-current Paramount logo with an orchestral rendition of "Love is a Many Splendored Thing." Post-1998 prints up to 2018 plaster this with the 1986-2003 Paramount Pictures logo with the Viacom byline and the "Paramount on Parade" fanfare. The 2018 40th Anniversary restoration 4K, Blu-ray, and DVD restore the original Paramount logo seen in 1978.
Although the movie was edited during the first couple of airings on BBC television (in the early 80s), the network now show the original 1978 cinematic version. Even still, the edits amounted to no more than three minutes. Although the BBC's editing department has done an abysmal job of deleting the song's "Grease Lightning" sexual references (the words, "tit" and "shit" - which were once 'hilariously' dubbed with the word "HIT" - and the phrase "pussy-wagon" were the only deletions amounting to a noticeable edit - a deletion of two lines from a verse), the 'TV-friendly' song number only lost 15 seconds from what was almost (?) a four-minute track.
UK Alternate (TV) Version: although the movie was rated (in the UK) as a 'PG' and usually received an early-afternoon TV screening (during the early 80's), most of the 'sexual references' featured throughout the movie (edited version) were kept in, mainly because of the cultural differences between the US and the UK. In other words, the terminolgy used by American 'teenagers' differs from their British counterparts.
Due to licensing issues, recent cable television broadcasts of 'Grease' feature a different soundtrack, with some original songs replaced by cover versions or by new tracks; this is most noticeable in the school dance-off scenes.
When shown by British network station ITV1 in November 2002, the entirety of the slumber party / 'Look At Me, I'm Sandra Dee' sequence had been edited, along with Rizzo's line to the T-Birds about a "gang bang", Kenickie's line "I hear you're knocked up" and Danny's line "sloppy seconds ain't my style". The 'Greased Lightning' number was entirely uncut.
The film originally had a Coca-Cola sign in the diner behind Olivia Newton-John and Lorenzo Lamas as well as several other Coke signs around the diner. Before the film was first released, the Coke painting seen in the diner had to be blurred out due to a deal made with Pepsi and not Coca-Cola, and all home media releases have also had this blur in front of the large painting. However, for the 40th anniversary release, editors digitally constructed Pepsi art over the place where the blur covering the Coke art was, making the cover up much less obvious and jarring.
The BBC television preview featured a version of the slumber party/Sandra Dee song in which the girls wore provocative lingerie and did a sexy dance routine which was from the 70mm roadshow version which has never been released on video.
All references to Doris Day in the Sandra Dee song were cut from early US video/TV versions.
