It might seem that life is just too busy to be polite anymore. But don't tell that to the folks at Main Street Theater, where Steve Garfinkel, along with the Emmy-nominated band Trout Fishing in America, has developed Ps and Qs: The ABCs of Manners. Shaped like a radio show along the lines of A Prairie Home Companion, the charming family musical follows what takes place one night both on and off the air of a radio broadcast while it tells us all about what happens to those of us who are perpetually late (just look at the poor "Late Great Nate MacTate"). And the Manners Police are always on hand to round up any soul naughty enough to take out her cell phone during the production. The musical features such silliness as a quiz called "Rude or Not Rude," and it even delivers a history of table manners, starting with cave times. And it reminds us that the most important rule of all is the golden one. Follow it and your manners will be impeccable.
