Did you also use the animation from the 1991 version of Grandma talking about Grandpa during the song? That was new animation done for that version that, in most people’s opinion, is more emotionally impacting that the original 1987 version.

The difference is that in the original 1987 version, she’s talking about grandpa and just sitting beside the window stroking Garfield.

In the 1991 version, while she’s still sitting beside the window, there’s a photo of her & grandpa on the window frame that better conveys how heartbroken she is that he’s no longer there.
