In the late 60's & early 70's, my taste in music did not include CSN or CSNY. I could only listen to AM radio back then and I hated Marakesh Express with a passion which of course was played way too many times. And then came Deja Vu and the overplayed singles were lame, lame, lame as far as I was concerned.
I can also add that CSN/CSNY jukebox records were overplayed in the bars I went to in those days. Green Eyed Lady by Sugarloaf and Little Green Bag by George Baker were overplayed as well but for some reason I liked those tunes.
No denying David Crosby was an influential musician and he may have broken ground in that trade but he was not involved in anything after The Byrds that turned my crank. And on a personal level, according to the press, he was a bit of jerk.
What rings true for me about a lot of the musicians who kicked in the last year or two, is that they were not much older than I am. So I pay attention because that old mortality flag keeps waving and waving, getting closer and closer.
Despite their popularity, I was not motivated to buy any CSN or CSNY albums when they were released. There are two or three in my possession now but only because they were cheap (used) and I felt a bit of nostalgia when I saw them. But I do not believe I spun any.
