I always enjoyed the Walton's show, too. It wasn't my most favorite, but it was high ranking.
I looked around for the intro theme, but this was the best that I could find that was the actual filmage and music. It's not of great sound or video quality, but it is original.

This one has the good music quality, but it is a pieced together work of video snapshots:

They both bring back some fond memories. Things have changed a great deal since the era of the depression as well as from the times that this series aired. The best times were probably when the series aired, but I think people's minds and hearts were more true and simple during the times that the series depicted. Today, very bad things are happening. Or is it just that I have changed? Or is it the media coverage?
For me, personally, "The Little House on the Prairie" series beat out "The Waltons". At least with the earliest episodes. For me, I felt that I would rather have lived during the time that was depicted in that show. I was also a huge fan of Michael Landon from the Bonanza series at the time, so that was a large appeal for me.
