Scooby-Doo
The first episode of "Scooby-Doo, Where Are You!" "What a Night for a Knight" debuted on the CBS network Saturday, September 13, 1969. The original voice cast featured veteran voice actor Don Messick as Scooby-Doo, radio DJ Casey Kasem (later host of radio's syndicated "American Top 40") as Shaggy, actor Frank Welker (later a veteran voice actor in his own right) as Fred, actress Nicole Jaffe as Velma, and musician Indira Stefanianna Christopherson as Daphne. Scooby's speech patterns closely resembled an earlier cartoon dog, Astro from "The Jetsons" (1962–63), also voiced by Messick. Seventeen episodes of "Scooby-Doo Where are You!" were produced in 1969–70. The series theme song was written by David Mook and Ben Raleigh, and performed by Larry Marks.
Shaggy &amp; Scooby-Doo Get a Clue!
Much like "The 13 Ghosts of Scooby-Doo" on ABC in 1985 (which had actual ghosts and monsters) and the "Scooby-Doo and Scrappy-Doo" shorts in 1980, this show is different from the usual "crooks masquerading as ghosts and monsters" series. Fred Jones, Daphne Blake and Velma Dinkley are downgraded, but not completely absent as they were in the "Scooby-Doo and Scrappy-Doo" shorts. They cameo in the first episode and have full guest appearances in another season one episode. Fred and Daphne appear as silent cameos in one season two episode when they were not allowed to Dr. Phibes's "attractive people" party. Their silhouettes run across the screen in the opening credits in amongst the silhouettes of all the show's regular cast.
