Who are the sixteen veswtigal virgins in a whiter shade of pale?

Oh, dude, you're talking about the song "A Whiter Shade of Pale" by Procol Harum. The lyrics mention "the sixteen vestal virgins leaving for the coast," which is a reference to the Vestal Virgins of ancient Rome. They were priestesses who tended the sacred fire of Vesta, the goddess of the hearth. So yeah, it's just a poetic way to describe a scene, not an actual list of names or anything.
