I too spent the whole of my teens in the '60s and stories of 'groupies' were rife, and reported at the time in the more salacious publications.

There is a hell of a difference between consensual behaviour that the 'groupies' indulged in and the unwanted assaults that have been reported with regards to the likes of Jimmy Saville and the one you described with your neighbour.

None of the cases that I can recall involving "celebrities" were ones of consensual behaviour but were out and out assaults.

The right or wrongs of sexual assault was not different 'then' - what is different is that such assaults are now treated seriously, rightly so in my opinion.
