From The Works 1984, “Keep Passing The Open Windows” is an uplifting song about life and opportunity.
“Keep passing the open windows” is a recurring phrase in John Irving’s 1981 novel “The Hotel New Hampshire”, which was made into a movie in 1984. Queen was approached to write the soundtrack for the movie, but the collaboration fell through. This song had already been written, however, and was included on Queen’s album “The Works”, released the same year.
The lyrics of the song make it fairly clear, but the book makes the message much more explicit: the “open windows” of the title are upper-story windows from which a fall would be fatal – in other words, “keep passing the open windows” means “resist the temptation to kill yourself”.
