Deletion of Grammy Award for Best Performance by a Vocal Group or Chorus

Comment: For large-scale awards programs such as the Grammies or the Oscars where awards are presented in ''many'' categories, the most useful presentation is for us to have a separate article about each year's ceremony that lists the winners in all categories for that year ''and'' a separate article about each category which lists the winners across the years in that category. Each category does not need to separately clear  on its own ''separately'' from the fact that the overall awards program has already cleared GNG, because the category is not ''really'' a standalone topic — the burden of clearing GNG is on the Grammy Awards as a ''whole'', not on each individual category. The separate by-year and by-category articles are a ''formatting'' choice; we spin off the separate subpages in order to keep the parent article at a manageable ''size'', not because each category is ''really'' a truly standalone topic ''independently'' of the Grammies as a whole. Yes, there's some potential for this to be improved, but it should be kept — because if it doesn't exist, then where is a user supposed to go to (a) ''compare''  the winners ''across'' the years in which it was presented, or (b) find any information about ''why'' it stopped being presented after 1960? If this category had been presented only ''once'', then we could justifiably redirect it to the article for that year — but if it was presented ''more'' than once, then there's an  competition between the years
