The pair marked their milestone anniversary in a magically musical fashion...
A couple marked their 60th wedding anniversary by sharing a sweet video of themselves performing a piano duet to the song Married Life, the tune from iconic Pixar movie Up.
The pair were helped by their grandson, YouTube pianist sensation Jason Lyle Black, and the video has already had over 500,000 views since being uploaded three days ago.
In the video's description, Jason wrote: "My grandparents were very excited to be part of this video. It was so fun to work with them on it. I’ve loved their piano duets ever since I was a little kid, so this will be a family treasure for all of us".
It was a whole family affair, with Jason telling ABC News: "The night we posted the video, we had the whole family together, and we had grandma's cookies. It was perfect".
In the movie, the sweet song is played during the opening montage, which shows main character Carl and his beloved wife Ellie throughout their marriage.
In Jason's grandparents' rendition, the couple - who are both 80-years-old - are shown sitting at a piano and playing the tune together. At the end of the video, Jason appears, dressed in a Scout uniform similar to that worn by Russell in the iconic movie.
The happy couple tied the knot in 1955, and have performed various piano duets together throughout their marriage. We'd argue that this is their best - isn't it wonderful?
