I was about 11 or 12 years old and listened to all the "pop" stations in Los Angeles, KFWB, KRLA, KHJ in the mid-1960's. I first became familiar with Joan Baez at that time after hearing her sing,
"There But for Fortune" which was played on all the pop stations.
I'd be listening to these stations play all the Beach Boys, the Beatles, Dave Clark Five, Jan & Dean, etc.
I was just a kid loving all the pop music and then heard this beautiful voice - and I COULDN'T BELIEVE IT!
These were all AM stations - not FM in those days.
So it was "THERE BUT FOR FORTUNE" being sung by Joan Baez on all these pop stations. (of course I didn't know who Phil Ochs was at the time - the writer of the song) and these stations did not play anything by Phil Ochs. From that day onwards when I heard Joan Baez for the very first time on the pop radio stations in Los Angeles - I was a fan forever and have just about every album of hers.
