I think “positron” was around long before JAM used the name 
Paul Dirac’s proposed anti-matter opposite of an electron if I remember my physics theory…?
Seriously though, as someone who collected jingles during the 1970s “weird Heller stuff” era but couldn’t hear them on-air (USA only…), did they ACTUALLY WORK as such with all the ultra-long LA-singers-Union-studiotime-rules cuts for chop-down and all the bizarre lyrics?
(The only aircheck I had of any that did seem workable on-air were short ones for WHN in New York – 1050 AM before it morphed through many further call-letter changes).
