I hope a show over 20 yrs old counts as a 'long lost show'.
There are a couple of odd shows I would love to see released.
First is SANFORD, Redd Foxx's sequel to SANFORD AND SON. The son was gone to Alaska but Fred was still danged funny!!
Marvel's cheap made-for-tv fare (Spider Man, Dr. Strange telefilm, the two Capt America telefilms). None of it very good but something odd enough to hold my attention.
