As you would have been reminded by John Cafferty and the Beaver Brown Band had you been listening to the radio 25 years ago, things are tough all over. And as Bruce Springsteen might have reminded John Cafferty, stop ripping me off, you Rhode Island poseur, things are tougher in New Jersey than they are anywhere else. Sad evidence of that today, with word that Toms River High School North music teacher Albert Crosta was arrested Monday after selling $1,300 worth of school-property musical instruments to a second hand shop. Clarinets, a violin, French horn and cymbals, everything.
