There was a Little House marathon on today, so it aroused my curiosity. I did some checking and found only this...
LITTLE HOUSE ON THE PRAIRIE Soundtrack Score (David Rose) .

It has the theme as well as some scoring samples. I was hoping that the music was out there somewhere.
Since he has passed, there is alas no web-site or samples, and no official release seems to have been done. Aside of course from the main title. This does not mean there were not samples available to someone. Something the composer gave to a friend, or fan etc. But I have never seen it mentioned anywhere.
