Scooby-Doo, Where are You!
Scooby-Doo, Where Are You! made its CBS network debut on Saturday, September 13, 1969 with its first episode, "What a Night for a Knight." The original voice cast featured veteran voice actor Don Messick as Scooby-Doo, Top 40 radio DJ Casey Kasem as Shaggy, actorFrank Welker 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 ofScooby-Doo were produced in 1969. The series theme song was written by David Mook and Ben Raleigh, and performed by Larry Marks and Paul Costello.
Each episode featured Scooby and the four teenaged members of the Mystery, Inc. gang: Fred, Shaggy, Daphne, and Velma, arriving to a location in the "Mystery Machine" and encountering a ghost, monster, or other supernatural creature, whom they learned was terrorizing the local populace. After looking for clues and suspects and being chased by the monster, the kids come to realize the ghost is anything but, and - often with the help of a Rube Goldberg-like trap designed by Fred - they capture the villain and unmask him. Revealed as a flesh and blood crook trying to cover up crimes by using the ghost story and costume, the criminal is arrested and taken to jail, often saying something to the effect of "...and I would have gotten away with it, too, if it hadn't been for you meddling kids!"
A ratings success, Scooby-Doo was renewed for a second season in 1970-71, for which eighteen episodes were produced. Seven of the second season episodes featured chase sequences set to bubblegum pop songs recorded by Austin Roberts, who also rerecorded the theme song for this season. With Stefanianna Christopherson having married and retired from voice acting, Heather North assumed the role of Daphne, and would continue to voice the character through 1997.
