Would like to add some recollections of Jack Carney's Comedy Show. A cousin of mine was a DJ at a station that ran the show, and gave me a big stack of the discs back in the 80's; I still have some. The series was originally syndicated as "Jack Carney's Comedy Store," which may have been its local title in St. Louis; I believe the owners of the Comedy Store night club in LA (and their lawyers) forced the title change. It was syndicated on LP discs by the Clayton-Webster Corp. which may also have been based in St. Louis. They also distributed a country countdown show; its title escapes me now though I had some discs of it as well at one time.
I do remember the short features; they were called "Jack Carney's Comedy Spot" and were added on to the same 2 LPS as the two-hour main show, by lowering the overall audio level (a la the K-Tel 20-hits-on-one-LP method, you really had to crank 'em up.) They were edited from the main shows and intended to serve as "teasers," they varied in length from 2 1/2 to 3 1/2 minutes, including a commercial. The "Comedy Spots" started a year or more into the show's run. Sponsors on the shows included Ford, Pillsbury, Kelly Springfield Tires, and State Farm Insurance (in certain regions only.)
If memory serves correctly, Robert Klein replaced Dick Cavett as host. Both Klein and Cavett re-recorded Carney's scripts word for word, including local St. Louis jokes; a record of the Guckenheimer Sour Kraut Band was announced as the "Knob Noster, Missouri High School Band." (Only years later did I learn who the real artist was!) After Carney's death, however, the producers apparently did not edit any new shows, but simply recycled Carney's programs with new "host" segments; the lack of new shows was probably a factor in the series' demise.
Carney edited his shows mainly from comedy albums of the 50's and 60's (Bob Newhart, Bill Cosby, the Smothers Brothers) and old-time radio sketches (Jack Benny, Burns and Allen, Fibber McGee & Molly.) All great stuff then and now, but with a "family fare" vibe that probably didn't appeal to stations looking for something "hip" and "edgy." It aired here on a full-service MOR station that later went to right-wing talk. And while Carney also included comedy musical numbers like Allan Sherman, Spike Jones, Stan Freberg, and David Seville; he wasn't really aiming at Doctor Demento's audience either. Still, I think the series would have lasted longer had they only invested in new episodes; and I wish there was something like it now.
