For many years a significant part of Davidson's output was Holophane stuff. It varied, but at a wild guess, during "my" time it might have amounted to 15-20% of total output. Three compositions purely for them.
I know I have mentioned this before, but one of the first things I noticed at Davidsons was that there were two brass plates on the front door. One of course was Davidsons but the other was Holophane. I was curious but I never did get a sensible answer as to the reason for the latter one. All the time I knew Holophane they were, as far as I knew, simply customers. What had been going on in the past goodness knows.
