Thanks for the correction, honoured Guest: as one who used to pull junked CRT-based TVs apart for a hobby*, I'm surprised that I missed that'n. The mention of Miss Lee's difficulties with getting the Lone Ranger ought to have clued me in.

Again thanks. I'll amend my working copy, but can't promise I'll remember to get it right on the night.
