After all the buzz, surely you want to see what it was all about. I refer to the Arkansas Tech production of "Assassins," briefly cancelled because of the college president's objection to use of blank-firing guns in the play. Tickets for tonight and Saturday are sold out. But you can still get seats for the Sunday performance on campus at 7:30 p.m. Reserve tickets ($8) by calling 479-968-0274. They won't be sold at the door.
