You can read the definitive FBWL listings here:

Hope this helps.
The jingles themselves are very short ( no more than 30-odd seconds) and serve as almost incidental 'linking' pieces on the FBWL project. They are interesting experiements with repetition and echo (ref the interview with Eno on FBWL) and give some light onto John's attempt to understand and ultimately create 'systematic' music.
Also fascinating as they represent a significant move away from the Metamatic project which was more or less left behind once the 80s began and Foxx travelled into Europe to defrost...
