Out of touch? - or maybe not.

Apparently, judges are to be given lessons in "social awareness" to try and ensure that they are up to speed with modern culture and mores - and to prevent the perceived embarrassment of them asking questions like "who are the Beatles?". Except that my understanding is that such questions are asked not necessarily out of ignorance, but as a way of ensuring that references to "passing fads" which may mean nothing to future generations are properly explained in the court records.  Everybody in court (including the judge) may well understand what is being referred to, but someone studying the case in years to come might well be at a loss unless it is spelled out.
