An elderly couple recently celebrated their wedding anniversary with a heartwarming piano duet from Pixar’s “Up.”

Their sweet video also incorporates elements from the animated film, including an “Adventure Book,” a family dog and even the tennis-ball cane.

The couple are the grandparents of musician and YouTuber Jason Lyle Black, who makes an appearance at the end of the video dressed in a Wilderness Explorer uniform just like Russell from “Up.”
