I haven't heard this KMJM breaker since 1981, but I still recall the promotion between songs for "the July Jam...Mmmmm...This one's blackberry. We're jammin' with more Summer magic on Majic 108 FM." I don't know if the station played more hits that month from July or Summer of various years, but Jean Knight's "Mr. Big Stuff," a Summer 1971 hit, played after it. If the station turned its playlist over to July or Summer hits, I wonder if the July Jam was an annual tradition or a one-time occurrence.
I'm still not sure of my own blood type--yet I still remember a station breaker and song from a tape that my stereo ate over 40 years ago.
