@hrc789,
Sorry I can't help.
What sort of family video is it?
What I mean by that is the motivation/character of the person making the video.
Are they the sort of person with established tastes, or are they the sort who is into the charts.
If they're the former it's likely to be from any time prior to 1983, but if they're the latte it may have been in the charts when the video was made.
Good luck.
