Review of The House Without a Christmas Tree

As a kid in the 70`s, I watched this program and throughly enjoyed it. This same cast also did a thanksgiving special called "The Thanksgiving Treasure" and neither are shown anymore. I thought that I saw them more than once, however, I never see them anymore.I sure would like my kids to see these. Lisa Lucas did an excellent job as Addie Mills. Why did they discontinue airing these two specials? Are these available to rent? Please contact me on availability, as I surely am interested.
