What I probably was listening to most this week...40 years ago. I don't remember when I actually bought Gordon Lightfoot's album Sundown -- though when I did, I bought the 8-track tape. (I was busy wrapping up my senior year in high school, so most other memories of that time have been swept aside.) But I have no doubt the title single, which had been released in February, was in heavy radio rotation by mid-May, en route to reaching No. 1 on the charts in June, so if I hadn't yet bought the tape, I certainly was hearing the song -- a lot. I've always thought Canadian folkie Lightfoot achieving genuine pop star status in the U.S. was a bit of a "lightning in a bottle" moment. Maybe the real benefit of the success of this record (which I still think is a great song) is that it set us up for 1975's devastating "Wreck of the Edmund Fitzgerald." (Album released January 1974)
