My wife and I were watching "Father of the Bride" last night with my blind grandmother. I noticed a very large framed print of Gregorian Chant in the movie. It's in the scene where George Banks (Steve Martin) goes to the future in-laws house, and excuses himself to use the restroom. He's snooping around the desk and looking at the bank book. On the wall just above what I believe is a towel rack on the right side of the screen, there is a very large print of Gregorian Chant notation. It was on TV, so I couldn't pause or replay to discern the chant, but it was there in plain sight.

So, feel free to list your chant sightings in this thread.
