This sound editor/sound designer/sometimes actor uses various name variants, and I'm wondering which is the "common" one for our purposes. The current CLT numbers are very close together, with, as usual, a lot of bad data to be found under the IMDb-name variant (mined data, effects editor credits, even uncredited work). Also note that the "Richard Steele" numbers are off thanks to other people named Richard Steele, for instance a British actor appearing in episodes of 'Dr. Who' and 'Special Branch' - that's not who I'm looking for here.
