When I heard this one the location was Waddo, the occasion was a Summer Ball (mid-70s - not later), and the young ladies were Newfie schoolies.
No doubt, the truth of this will remain as elusive as the coachload of Swedish nymphomaniacs that 'happened to leave this morning'.
Must add that January has brought some great additions to 'Vulcans in Camera'.

Thanks to the readers of this forum who have submitted images. If I receive many more pictures of 'Vulcan People', I shall have to spin them off onto a new site.
Additions, captions, amendments welcomed.
