Sesame Street At Night? (found 1977 PBS special, hosted by Gene Shalit)

Sesame Street at Night? is a half-hour PBS special that aired in March of 1977 to celebrate Sesame Street's 1,000th episode. Gene Shalit hosted the special, which also featured a Muppet lookalike of the critic. Featured segments included Grover and Lena Horne singing "How Do You Do?" While Betamax was already common in some homes at that point in time, for some reason no one has come forward with a recording. Only a few press releases and photos as well as an article on the Jim Henson's Red Book blog (run by the Jim Henson Company) prove that this special existed. (And no, the question mark in the title of this article is not a typo, that actually is the special's name; it's loosely based on a critic's remark when Sesame Street first came out - "it's too good for kids".)
