Hey, Hey, Hey, It's Fat Albert (Lost Primetime 1969 Special)

Fat Albert and the Cosby Kids is a animated TV series which aired from September 9, 1972 to August 10, 1985. It has 114 expisodes counting specials. Before the series premiered, there was a primtiem special called Hey, Hey, Hey, It's Fat Albert, which was showed November 12, 1969, and aired on NBC. It was only rebroadcast twice. It follows The Cosby Kids performing stand-up sketches from Bill Cosbys routines, much like in the actual show.

The special has a very different style from the later series. Due to time and a tight budget, the animators had to draw directly onto cells with grease pencils and actual images of Philadelphia were used for backgrounds. The music was provided by Herbie Hancock, who later used some of the music he composed on his album Fat Albert Rotunda. Unlike the later "Cosby Kids" series and specials, it has not been released on DVD. (Wikipedia).

While the series became popular, the special has not showed up anywhere. It seems that either the original tape was lost, or they simply just didnt care to release it.
