Well, call me old-fashioned, but I believe that its all a matter of rights AND responsibilities. Obviously everyone should have the right to sing at singarounds but with that right comes a RESPONSIBILITY to entertain your audience and fellow singers - not subject them to an excruciating ordeal! Often that comes down to putting the work in beforehand. I think that the MINIMUM effort that a singer should put in is to learn the words of his/her song(s). And please don't give me that crap about poor/defective memories! Often the excuse of a 'poor memory' hides a bad case of 'lazyitis'. If anyone turns up at the singaround that I attend with a crib sheet, I just assume that they're a lazy git ... unless, of course, they produce a doctor's note ...
