I am crestfallen over the fact that Cannon’s my favorite bar since long before the age when it was legal or parentally permitted for me to have favorite bars is closing this week forever. It’s been around since the 1930s — on 108th and Broadway — and I will miss it terribly. Last week the New York Times dubbed it the “the last of the area’s scrappy watering holes” — which barely does it justice. It was one of the classic bars which never got so seedy to be a full-blown dive but never got so pretentious to lose its mix of souses, blue-collar working guys and college and (in my day) high school kids playing quarters. Farewell.
