True, the song goes back quite a ways and the audience has aged. Much like when I attend the occasional folk coffeehouse up in Essex and you see a lot of white/grey-haired folks. The audience is getting up there in years. Similarly, I listened to a podcast of a show called Baby Boomer Favorites and they were doing "answer records" to songs like The Wanderer,
The Lion Sleeps Tonight, and At The Hop. Hearing songs like that from late 50s/early 60s, I thought to myself it's been awhile since stations like WODS played them, and it was actually a bit refreshing to hear them. But there's a reason why
sock hop faves aren't on 103.3 anymore: the demo they want is a bit younger than those who grew up with that music.
The day may come when they drop Beatles, Beach Boys, and Motown, one would think.
Another song they played was a response to Duke of Earl by Gene Chandler, a song that was #1 the week I was born
in early Feb. of 62 (the following week: Peppermint Twist). Well, I think Arlo's song came out in the year of Sgt
Pepper and the Summer of Love when I was 5. When was the draft abolished, 73 or so? I was 11 then and didn't have to worry about being drafted. (For that matter, an episode of the TV cartoon Wait Til Your Father Gets Home revolved
around a college-age student possibly being drafted,and thinking of fleeing to Canada. It came out in 72, when there still was a draft.) Indeed, Arlo's song is
based around that idea, and as Neanderpaul said, it's been quite awhile since then.
Though some stations around do appeal to that older audience--WJIB comes to mind--and there are some stations like mine who will air shows like "Uncle Henry's Basement" (doo wop/group sound) and "Kaleidoscope Moodrops Falling"
(the psychedelic rock sound). Those who grew up with each type of music right now may well be AARP members.
