As far as I can tell, this Robin Richmond was mentioned in an August 1990 article in Keyboard Review magazine, and has been immortalized on a CD track titled "Taboo - Robin Richmond", produced by the 'conceptual art' DJ group KBZ 200 who specializes in marathon performances of various versions of only three different songs (one of which is, of course, "Taboo").
the Robin Richmond from the Richmond Lab at the Institute for Molecular Biology und Biophysics ETHZ,
