The answer to our trivia question this month (see original thread below for details) is Vassar Clements, who replaced Chubby Wise in Bill Monroe's Bluegrass Boys.
Our winners this month are David Brown and Bob Palasek. I flipped a nickel to determine the winner of the tee shirt prize and it landed with Jefferson's face upright. That means David gets the new threads this time. Sorry Bob. But congratulations to both!
