Thanks, folks. I'm delighted that it pleased and didn't cause too much stress with regard to the sixth highlighting colour for instance. Cockie (comment 13) there was a long editorial discussion about this (between a setter who is oY and an editor who is 'adopted' oY).The R in question, as well as being oG, was the very last of the Y kings and also held the oY title. We felt that the Bosworth title was a much better hint to solvers who mosty think it is that RoY that the mnemonic refers to than, say, 'In Wakefield Field'. (But you are the only person, so far, to have noticed the slight anomaly.)
