I don't think we should judge "yesterdays" actions by "todays" standards.
Bear in mind that DJs and Pop Artists had a following of "Groupies". When
faced with Groupies what was a bloke expected to do (by his peer group and
by the groupies). as far as the BBC is concerned, I expect they felt some
sort of duty to allow stars some access to their fans. It was a long time
ago!
