I first read about it here, on the Brady Bunch chat forum, several years ago and lamented to find that the program only aired once and was thought lost.

Until now, that is. Guest stars include Florence Henderson (natch) and other mid-1970's stars, like KISS and Billie Hayes, you hate to love and love to hate.

Wow! Thanks for posting that!

That one should definitely be worth a look just for the historical value! I just read the reviews on Amazon.com ... a very interesting cast :)
