I, too, caught most of today's 1971 countdown. Fascinating stuff. I was surprised at the number of "hits" that I do not recall, probably due to being too young at the time, combined with the fact that many just don't get airplay anymore. I was also somewhat surprised at the numer of R&B hits, but now that I think about it, this was not an "airplay", countdown, it was a "sales" countdown, and those R&B hits certainly sold. I would suppose KJR-AM (who ran this show in the 70's), played perhaps 70% of this chart. I know they stayed away from a lot of the R&B, for sure.
Also interesting is just the pure variety of this countdown. Everything from James Brown to Donny Osmond to Helen Reddy to John Denver. And frankly, a lot of the songs on this countdown don't deserve airplay today, some were pretty bad. A good reminder that every era has its share of garbage.
Casey, himself, was rather subdued here, acting more as a historian, than a host. And the fact that they threw in a Nat King Cole song from 1951, and Mark Dinning's "Teen Angel" tells us this was a different time indeed.
But, I'm now hooked. Great stuff.
