I wasn't a flower child as such, but I grew up in England in that era and was right into the music that became known as 'The British Invasion': The Beatles; The Rolling Stones; Ten Years After; Jethro Tull: Cream; The Who, etc, etc. I did have the pleasure of seeing Jimi Hendrix at the Isle of Wight Festival, however, along with Jethro Tull and several others. Yup, those were the days, when music was music, and not some twit fast talking to some scratched record getting dragged arse backwards.
I wasn't allowed to have long hair in those days as my father was strict on that sort of thing... I wasn't a girl, so it was off to the barber once a fortnight for a short back and sides. It wan't until I turned 18 in '71 and I had 'mostly' moved out of home that I was able to grow long hair... and I did it with a vengeance after all my mates had long hair and I couldn't. It eventually came 3/4's the way down my back, and when my fringe was brushed forward it came down to my belly button... it pretty much stayed that way until about 4 -5 years ago when I started having greater issues with the Oz summer heat.
It's funny, isn't it, how things change yet stay the same! My father would say to me: "What are you listening to that bloody rubbish for?"... and a few years later I'd hear my son listening to rap music and say the exact same thing.
