This is one of my fav's. The only reason I found it was because I was researching Chris Stapleton at the time, long story. So basically the story goes the daughter filmed her daddy, and before she knew it, it went viral around the world. Only problem, like everything it became tv famous and spoilt the capture of the moment, but hey still worth a listen...
and if it's a tear jerker you want, then Quando, quando, quando is just that, when you know dad has dementia If you want to know more about Ted's story... https://en.wikipedia.org/wiki/Songaminute_Man
