Never saw before stumbled upon today on one of the retro channels we get with our digital converter box, sorta like Wonder Woman ... can check to see if in your area too :) http://watchpbj.com/
Bell bottom blues you made me cry... I don't want to loose that feeling.
Isis is currently airing on Retro TV Saturday afternoons at 12:30 P.M. Eastern time, followed by a New Adventures of Pinocchio short (remember, when Isis originally aired on CBS in the mid-70's, it only ran 25 minutes - and was filmed as such, without any cuts - in order to make room for those In the News shorts following the program).
Be cautioned, however - the audio is sped up by 4%; this was because, way before their current ownership by DreamWorks, the Filmation shows were once owned by a British company and were converted to the PAL system, causing playback to sound way off-pitch. If you can endure that, however, seeing Isis again will bring back many nice memories for those like myself who first watched it in the 70's.
