Here's a collection of license plates from some Nashville radio stations of the 1970s. Click any image to enlarge, and if you have any of these to show, post a link in the comments section.
WLAC -AM was still top 40 when this came out.
WSM-AM was news/talk all day and country at night, including the Grand Ole Opry Saturday nights.
SM95 was WSM-FM, soft pop and west coast rock.
Here's a bonus plate, the Exit/In, Nashville's hip spot for every kind of music in the 70s. Among the acts I saw there were Barefoot Jerry, Harry Chapin, Jan Hammer, and Stanley Turrentine.
