I was learning guitar at a time in the late 1960s when pop music went very weird and psychedelic - not really suitable for a 12 year old with no acces to drugs and knowing only 3 chords on an acoustic guitar. I cam across a book of folk songs which had stuff I could play. That led me to the Spinners on TV and "Folk on Friday" on radio. Eventually I was old enough to start going to folk clubs.
