I remember exactly where I was the first time I heard it. I went west (California) for a job interview and I heard it on the rental car radio on the way from LAX to the hotel. I believe it was around 7/10/76. It turned out to be a fateful interview because I ended up going setting in motion 15 years of missed winters including the blizzard of '78. That said, what happpened in those 15 years helped set the stage for a return and some nice late career success.
