wbhist said:The mid-show I.D. on that Howdy Doody series finale was voiced by Bill Hanrahan, who within a few years became the "Voice of NBC News." The promo for the upcoming National Velvet series was V/O'd by the late Bob Waldrop - who one night in 1960 after the network's New York flagship changed call letters from WRCA-TV to WNBC-TV did a sign-off that was recorded by one Jerry Immel, and is now on J. Alan Wall's TV Signoffs site in a section dealing with audio-only sign-offs of TV stations from the mid-to-late 1950's to early '60's.oldschooler1 said:There's also a Youtube link to the final Howdy Doody episode---the original network broadcast. It includes a mid-show net ID slide for station break, plus at the end of the show, the network promo (just a couple slides) for the movie "International Velvet" that aired the following Sunday night. "Eight eastern and pacific, 7 central, on NBC!" Good stuff!
Jerry Immel was also the source of the Bill Randle Show referenced above (or on the previous page)
