That kinda started to come in during the mid 70's where status was everything.
The 60s chicks who hung around bands at the time were just as likely to be with someone from The Association as they were The Stones if that is where the music lead them.
It wasn't just a matter of bed hopping and the sex, they did the laundry, they cooked them meals and the musician's sort comfort within this if they were on the road for a long time.
It gave life some normalcy.
When these girls were with someone, they weren't with anyone else as they really did believe that one day they would become Mrs Page/Jagger or whatever and everytime they were left heartbroken.
It is a very different story come the late 70s/80s it got very ugly.
It still goes on today yet it's different again; you will find groupies belong to a burlesque dancer group or something similar and that is the only in to reach the bands.
There are still known names within that scene.
As for Carnaby Street- I was disappointed too.
Meas, you say the Strips the same!!! gutted.
On a plus... last year I was walking down Portabello Rd and the Stones Get Of My Cloud was playing on the radio from one of the shops, that made me smile as I was transported back and was just soaking up the atmosphere! lovely!
