We've recently added Trivia as part of our slow weekday shows... It works great.
What I do is prepare 32 questions 8 per round for 4 rounds. We do slides (JPG or GIF) for showing the questions on the screen as we read them. The rotation goes as follows... Singer, Question, Singer etc etc... after the 8th question we give the answers for scoring and give away a prize using a drawing... end of the night sheets are turned in with totals.... high score wins..... timing works out just about perfectly. We start at 9 PM and finish usually within 15 minutes of 1 AM... if the place is busy we'll run singers till 2....
Anyone with other ideas? if you want to see the slides and how we do it just send me a message here or
