I have to jump on here and stick up for Pepper Tanner jingles; they weren't as fresh and tasty as PAMS, as slick and imagey as TM, but they're far from being the worst. Pepper actually scored some important radio stations as clients, including WIBG having defected from PAMS to run It's What's Happening in 1965; in 1964 at least one of the major Top 40s in almost every rated market ran The Station That's All Heart, and in 1974, WFIL abandoned PAMS for the TSOP package, which was done by Tanner's Thunder Productions division.
Pepper made station ID jingles affordable for everybody, allowing stations below market rank #100 to have singing IDs. All you had to do is run spots for Frosty Root Beer.
In the waning moments of my own jingle collecting, the remaining pieces I'm looking for are pepper jingles from WAAT, WEEZ, and WMID...who ran the All Hearts for one year. And the CRC package for WMID that no one seems to have.
According to a story I was told, there was a day when Pepper Tanner decided to trash all of the reference copies of their jingles, all in those ruby red reel boxes...and a well known collector was "shoveling" them into the back of a truck...and this guy refuses to share them with anyone. If anything happens to him, all that history is lost.
