Hand pulled Boy: no, I was not describing "open mic nights". At such events, I would expect microphones, and I would expect that musicians casually dropping in would get a chance to play. And I would not be disappointed as that is exactly what happens. What I was objecting to is pub music being desribed as "acoustic" when it is in fact "amplified". I appreciate that words change their meaning: but it is confusing when words are used by some people in a sense completely opposite to their original meaning, as understood by ordinary right-thinking people, such as myself.
