1980 Analog Disk Jocky dreams...

"You're listening to WKLA AM and FM in Ludington Michigan, Mason 
county's home of Deeeeetroit Tiger Baseball.  We'll get back to the 
game after these words from Acme Distributing, the very tops in adult 
beverages."

Yeah, that was what was paying the bills.  18:00 to 01:30, Evening 
announcer, log keeper - I perfected my 'Initials' having to physically  
sign off on every spot (Ad) that was aired  on my shift.  Loader  of 
automatic cart carousels - "the program" unless ... I took over the 
air  waves.

After Midnight was an off-the-books live Jazz program.  One of the 
really great unrealized resources of this and many small market 
stations is the  depth  of their vinyl (physical) collection.  Even 
though  they billed themselves and played mostly C&W (REAL C&W, not 
this modern cr*p) they had  a  FULL library, of mostly unplayed LPs.

Combining the records with a knobs-and-vu-meters console and 
professional turntables made for heady times.  Live radio was episodes 
of thinly veiled panic between periods of luxuriating in the music.  
Reading liner notes, drifting through Miles' Kinda Blue or Coltrane's 
Favorite Things, and then trying to remember what is que'ed up next.

Queing vinyl cuts for air play on a turntable might have been the 
original form of Scratching.  Pot up the audio queing feed, set the 
needle in the empty space, manually spin forward until the start  of  
that  track's audio then spin it a half  turn back - so that  when the 
turntable was energized it would be up to speed when  the  audio  
began.  Pot the que feed  down  and  go back to the  live  feed.

I learned about some of the lineage of Jazz.  An example was finding 
out who Red Nickes & The Five Pennies were.
