-- An elderly couple's musical rendition of the Disney movie "Up" is tugging at the Internet's heartstrings.
The couple's "Up" recreation is complete with various elements from the movie including Carl's tennis-ball cane, the "Adventure Book" and even a "Squirrel!" reaction from the family dog.
The couple's grandson makes an appearance at the end of the video wearing a "Wildnerness Explorer" uniform like Russell in "Up."
Black wrote the arrangement for his grandparents, he told ABC News, adding that "Grandpa and Grandma have played piano duets since they were first married" in 1955.
"They really loved the movie, and it was incredibly fun working with them for the video," Black said. "They've loved music their entire life. The piano they're playing in the video is actually a restored antique Steinway from the 1800's."
Black added that he "loved their piano duets ever since I was a little kid" and that the video is a "family treasure" for the couple's nine kids and over a dozen grandchildren.
"The night we posted the video, we had the whole family together, and we had grandma's cookies," he said. "It was perfect."
