Lyric discussion by song4julia 

The title was taken from a statement Ringo made while filming the movie. He was walking out of the studio after a long day of filming and said, "It's been a hard day.....day is night." after he looked up and noticed it was night time. It is a perfect title song for this wonderful movie.

i deffinetly agree!! AWESOME movie!!!! my favorite part is ( " the old man is probably having an orgasm" john-"ORGASM??!!!!!!" all four guys run out of the room) lol LOVE IT!!!!!

@song4julia He actually coined the phrase a long time before the filming of the movie (after a recording session). Inspired by Ringo's utterance, John used the phrase in his book "In His Own Write" and then remembered it after a hard day's...erm...work...during the film! Some time later it was suggested as a film title, whereupon John set about writing the song (anxious to beat Paul to the task!) @LovelyRita41 - the word is ORGY not orgasm (sounds like you need to look it up in the dictionary!)
