Whatever happened to the Robert Smith lookalikes?

In the late 80s and early 90s it seemed as if every British higher education institution had at least one Robert Smith clone. Skulking in the shadows at the Students' Union disco, these devoted creatures would only venture into the glare of the strobe lights at the familiar sound of the opening bars of The Love Cats or Inbetween Days, disappearing again as quickly as they emerged. Who were they and what happened to them all? Some enterprising documentary maker should let us know.
